6da05ab150 package/Makefile.in: adjust LDFLAGS for elf2flt
So far, our LDFLAGS for the BR2_BINFMT_FLAT case were only used on
Blackfin. However, passing -elf2flt in LDFLAGS is wrong. Indeed,
LDFLAGS are not linker flags, but flags passed to the compiler when
linking.

If you pass -elf2flt to the compiler when linking, it is understood as
"-e lf2flt", i.e "the entry point is named lf2flt", which isn't
exactly the intention. We in fact need to pass -Wl,-elf2flt in LDFLAGS
as well, so that the compiler passes -elf2flt down to the linker.

For some reason, this option does not cause an issue with the Blackfin
toolchain, but it does with either a Buildroot toolchain for Cortex-M
or an OSELAS toolchain for Cortex-M. We have verified that passing
-Wl,-elf2flt continues to work with the Blackfin toolchain.

dc95d50fe3 package/Makefile.in: correct gettext handling for musl
Based on a patch by Bernd Kuhls.

The AM_GNU_GETTEXT autotools macro misdetects musl gettext support as it
checks for internal glibc symbols.  Work around it by forcing libc gettext
support when musl is used for the supported gettext api levels.

As this is a generic issue for any package using AM_GNU_GETTEXT, add it to
the global TARGET_CONFIGURE_ARGS instead of for each affected package.

d29c7196bf toolchain: granular choice for stack protector
Currently, we only support two levels of stach-smashing protection:
  - entirely disabled,
  - protect _all_ functions with -fstack-protector-all.

-fstack-protector-all tends to be far too aggressive and impacts
performance too much to be worth on a real product.

Add a choice that allows us to select between different levels of
stack-smashing protection:
  - none
  - basic   (NEW)
  - strong  (NEW)
  - all

The differences are documented in the GCC online documentation:

d82f69cf10 infra: move ccache handling to the toolchain wrapper
Since we always have a toolchain wrapper now, we can move the ccache
call to the toolchain wrapper.

The hostcc ccache handling obviously stays.

The global addition of ccache to TARGET_CC/CXX is removed, but many
individual packages and infras still add it. This means we have a
chain like this: ccache -> toolchain-wrapper -> ccache -> gcc
However, this is fairly harmless: for cache misses, the inner ccache
just adds overhead and for cache hits, the inner ccache is never
called. Later patches will remove these redundant ccache calls.

As a side effect, perl now supports ccache as well.

8b525dc934 package-infra: add helper to build kernel modules
The Linux kernel offers a nice and easy-to-use infra to build
out-of-tree kernel modules.

Currently, we have quite a few packages that build kernel modules, and
most duplicate (or rewrite) the same code over-and-over again.

Introduce a new infrastructure that provides helpers to build kernel
modules, so packages do not have to duplicate/rewrite that.

The infrastructure, unlike any other package infra, is not standalone.
It needs another package infra to be used. This is so that packages that
provide both userland and kernel modules can be built easily. So, this
infra only defines post-build and post-install hooks, that will build
the kernel modules after the rest of the package.

We need to override PWD, because some packages will use it to find their
own includes (and other helper files). PWD is inherited from the
environment, so it gets whatever value it had when make was launched,
which happens to be Buildroot's own top source tree. So, we just force
PWD to the proper value, rather than cd-ing first.

Also, no host version is provided, since it does not make sense to build
kernel modules for the host.

1668e1da39 packages: fix and improve support for top-level parallel make
The boost and jack2 packages fail to build when PARALLEL_JOBS is empty
so instead of using an empty PARALLEL_JOBS don't use it in the MAKE
variable when top-level parallel make is being used.

To simplify the use of top-level parallel make, check the MAKEFLAGS
variable to know automatically if the -j option is being used, also use
the "=" operator instead of the ":=" operator because the MAKEFLAGS
variable can be checked only in a "recursively expanded variable".
The "override" keyword must be used in order to change the automatic
variable "MAKE".

When the top-parallel make is being used the sub-make are called without
specifying the "-j" option in order to let GNU make share the job slots
specified in the top make. This is done because GNU make is able
to share the job slots available between each instance of make so if you
want to increase the number of jobs you just need to increase the <jobs>
value in the top make -j<jobs> command.

If we specify the -j<jobs> option in each instance of make, it is less
efficient, e.g. in a processor with 8 cores we specify -j9 in each instance:
the number of processes goes up to 81 because each sub-make can execute
9 processes. The excessive number of processes is not a good thing
because in my tests even -j16 is slower than -j9.
Instead if we don't specify the -j<jobs> option in the sub-make, the top
make share the job slots automatically between each instance, so the
number of process in this examples goes up to 9 that is faster than
using up to 81 processes.

e.g. when the -j3 option is specified only in the top make:

possible state n. 1:
process 1 - <packagea>-build
process 2 - <packagea>-build
process 3 - <packagea>-build

possible state n. 2:
process 1 - <packagea>-extract
process 2 - <packageb>-configure
process 3 - <packagec>-build

possible state n. 3:
process 1 - <packagea>-build make -j1
process 2 - <packageb>-build make -j1
process 3 - <packagec>-build make -j1

a9847d1483 Makefile: delete HOSTFC and FC_FOR_BUILD
This definition of HOSTFC is completely wrong.

"$(HOSTLD)" should be "$(HOSTFC)".  Also, "echo" always succeeds, so
"which g77 || type -p g77 || echo gfortran" is never run.

Anyway, HOSTFC is most likely set to "/use/bin/ld" and nobody has

e91dfc68d7 br2-external: make it available to post-{build, image} scripts
Currently, BR2_EXTERNAL is not always exported to sub-processes that we
spawn, like post-build or post-image scripts. This all depends on how
the user passes BR2_EXTERNAL; consider the following:

  - make BR2_EXTERNAL=/path/to/br2-ext
  - BR2_EXTERNAL=/path/to/br2-ext make

In the first case, it is just a make variable, not an environment
variable, and thus not exported, while in the second case it is an
environment variable and gets exported to all sub-processes make may
spawn.

Explicitly export it using EXTRA_ENV.

158001f57b Turn the static lib option into a choice with more options
This commit turns the single static option into a choice, which offers
various possibilities:

 1. Build and use static libraries only;
 2. Build both shared and static libraries, but use shared libraries;
 3. Build and use shared libraries only.

On most platforms, (2) is currently the default, and kept as the
default in this commit. Of course, on certain platforms (Blackfin,
m68k), only option (1) will be available.

In addition to the introduction of the Config.in options, this commit
also:

 * Removes the 'select BR2_STATIC_LIBS' from 'BR2_BINFMT_FLAT', since
   with the use of a choice, we are guaranteed that BR2_STATIC_LIBS
   will be selected when the binary format is BR2_BINFMT_FLAT, since
   BR2_STATIC_LIBS will be the only possible solution in the choice.

 * Changes package/Makefile.in to use the proper
   --{enable,disable}-{shared,static} options for autotools packages.

Yann E. Morin.]

665e13c85e Rename BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS
Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.

As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.

This also helps preparing the addition of other options to select
shared, shared+static or just static.

Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

4ac8f78d37 Add option for paranoid unsafe path checking
This commit adds a Config.in option to the "Build options" submenu to
enable paranoid checking of unsafe paths. This mechanism is added as
an option so that when we'll enable it in the autobuilders, people
trying to reproduce the build failures will be able to do so by just
downloading the configuration file. If instead we were leaving this
feature as an environment variable, everyone would have to remember to
pass this environment variable to reproduce build issues. And certain
build issues triggered by paranoid unsafe patch checking may not be
visible in the build output, for example when they happen during the
execution of configure scripts.

Since this option is fairly advanced, a new submenu inside "Build
options" is created, for Advanced options.

514d7cab61 infra: do not append an empty LD_LIBRARY_PATH
When we set LD_LIBRARY_PATH when building our host tools, we append any
pre-existing value to our custom path:
        LD_LIBRARY_PATH="$(HOST_DIR)/usr/lib:$(LD_LIBRARY_PATH)"

But then if LD_LIBRARY_PATH was previously empty, we end up with an
LD_LIBRARY_PATH that ends with a colon.

Also, when we check that an existing LD_LIBRARY_PATH does not contain
CWD, we previously did not look for a zero-length prefix.

Since 'man ld.so' says of LD_LIBRARY_PATH:
    A colon-separated list of directories in which to search for ELF
    libraries at execution-time. Similar to the PATH environment
    variable.

And POSIX states about PATH:
    A zero-length prefix is a legacy feature that indicates the current
    working directory.

And bash also recognises a zero-length prefix to search in CWD:
    A zero-length (null) directory name in the value of PATH indicates
    the current directory.

We may thus end up on a system where a zero-length prefix in
LD_LIBRARY_PATH is interpreted as CWD.

Do not append the previous LD_LIBRARY_PATH if it was empty, and check
for a zero-length prefix when checking dependencies.

Currently, the variables PERL and PERL5LIB are available only during
the configure step of host-intltool, but they are also needed when
running host-intltool, in all packages that depend on
host-intltool. Without them, host-intltool cannot work as it doesn't

This commit therefore makes the PERL and PERL5LIB variables global, so

822a757456 infra: Move --enable/--disable-debug to package/Makefile.in
A lot of packages ignored BR2_ENABLE_DEBUG. This patch simplifies the handling of
this option by adding the corresponding configure option to the global Makefile
for target packages.

For host packages --disable-debug is added to the global Makefile.

3c25f6e6c0 package/Makefile.in: Fix dependency for selecting uclinux as TARGET_OS
Current setting only allows blackfin to select uclinux as TARGET_OS.
However, some noMMU ARM platforms that using FLAT binary format also need to
select uclinux as TARGET_OS. Fix the dependency.

3ed0eada71 Makefile: unconditionally include pkg-utils.mk
Currently, pkg-utils.mk (included via package/Makefile.in) is only included
when a configuration file already exists. This means that none of the
utilities it defines are available without .config.

In particular:
- the MESSAGE macro, causing pretty build output. Since some make targets
  can be run even without .config, like 'make manual', not having this
  pretty printing is odd.

- pkgname, pkgdir: in a subsequent patch, these functions will be used for
  the generation of the manual, and since this should work also without
  .config, we need these functions to be available.

This patch moves the include of pkg-utils.mk from package/Makefile.in to
Makefile, outside of the check for .config.

This is a quick fix. The full solution involves to minimize the amount of
Makefile code that is guarded by a check on .config. This approach will be
taken in the 2014.11 release cycle.

abb8a8dae4 infra: introduce a kconfig-package infrastructure
There are several packages that have a configuration file managed by
kconfig: uclibc, busybox, linux and barebox. All these packages need some
make targets to handle the kconfig specificities: creating a configuration
(menuconfig, ...) and saving it back (update-config, ...)

These targets should be the same for each of these packages, but
unfortunately they are not. Especially with respect to saving back the
configuration to the original config file, there are many differences.

A previous set of patches fixed these targets for the uclibc package.
This patch extracts these targets into a common kconfig-package
infrastructure, with the goals of:
- aligning the behavior of all kconfig-based packages
- removing code duplication

In order to use this infrastructure, a package should at a minimum specify
FOO_KCONFIG_FILE and eval the kconfig-package macro. The supported
configuration editors can be set with FOO_KCONFIG_EDITORS and defaults to
menuconfig only.
Additionally, a package can specify FOO_KCONFIG_OPT for extra options to
pass to the invocation of the kconfig editors, and FOO_KCONFIG_FIXUP_CMDS
for a list of shell commands used to fixup the .config file after a
configuration has been created/edited.

cbffd50561 toolchain: Add config option for atomic intrinsics
GCC has several builtin functions that implement atomic operations. Those
functions are architecture specific and may not be implemented by the
specific toolchain. In case of GCC for ARC those functions rely on
LLOCK/SCOND instructions which are optional in ARC CPU's. If ARC CPU doesn't
support those instructions but software tries to use them, then application
will be aborted with Illegal instruction exception. To avoid confusion user
should first specify that their CPU supports atomic extension, which will
allow selection of packages that use builtin atomic functions.

This variable contains extra environment variables that we can not export
since they are clashing with some build systems (eg. BUILD_DIR with
u-boot).

So, we may need these variables for uses other than the user's hooks
for instrumentation. For example, we'll use them later on to export
BUILD_DIR to the download helper scripts.
