49d97993d8 arch: define dependencies for the binfmt flat formats
The situation looks like following for elf2flt and binfmt FLAT:

 * Only gcc for bfin/m68k implements
   -msep-data (BR2_BINFMT_FLAT_SEP_DATA) and
   -mid-shared-library (BR2_BINFMT_FLAT_SHARED), so the corresponding
   options are made only visible on those architectures.

 * When the default of BR2_BINFMT_FLAT_ONE is used on m68k, broken
   binaries are produced, which mainly end up in SIGILL, so do not use
   it for m68k.

633f20002e i386: properly define BR2_ARCH for all x86 subarchitectures
We were not defining BR2_ARCH for two of the x86 subarchitecture,
which means the architecture part of the GNU_TARGET_NAME tuple was
empty, leading to weird build failures.

This commit fixes that by defining the appropriate values.

Fixes bug #8861.

6cb4814c87 arch/x86: remove support for i386
The Linux kernel doesn't even support i386 anymore, there is no NPTL
support for i386 and uClibc-ng only supports NPTL on x86, so there is
essentially no usable thread implementation. Most likely glibc and
musl also don't support i386 either. So it's time to remove the
support for this architecture variant.

41bcc440b1 arch/arm: Cortex-M3 provides only Thumb-2
The Cortex-M cores only support Thumb-2, not Thumb. In fact, Thumb-2
is a superset of Thumb, and we could have a single option for both in
Buildroot, since -mthumb on ARMv4/v5 means original Thumb, while
-mthumb on ARMv7 means Thumb 2. However, for clarity, it makes sense
to have two separate options. But in this case, Cortex-M3 should not
advertise that it supports Thumb, as in fact selecting Thumb would
generate Thumb-2 code.

f52692ed64 arch/arm: add option to enable an optional VFP unit
Currently, the VFP selection for ARM is a little bit muddy:
  - some CPUs definitely do not have a VFP or NEON,
  - some CPUs definitely do have a VFP or NEON,
  - some CPUs may have a VFP or NEON.

However, we currently conflate the availability of the VFP/NEON with the
possibility to use them. Even is the user chooses a floating point
strategy with a 'lower' solution (i.e. VFPv2 when a VFPv3 exists, or not
using NEON when the CPU has it), some packages are still using the
CPU-defined HW availaibility rather thean the usr's selection.

Furthermore, for CPU that may have a VFP/NEON, there is no way for the
user to actually specify that the HW is indeed available; the user can
only specify the floating point strategy. This means that some packages
or some package versions, like nodejs for example, can not be properly
selected on some CPU cores, like Cortex-A9 which only may have a VFP.

Like we have an option to enable an optional NEON unit, add a similar
option to enable an optional VFP unit.

b64bcbf5f2 arch/arm: reorder NEON option
Stating whether to use the NEON extensions when it is optional in the
CPU really is completing the definition of the CPU we've just selected.

Move the ENABLE_NEON option just after the choice of the CPU variant,
and before any "software" option (ABI/VFP).

This will make sense in a moment, when we introduce a similar option for
enabling an optional VFP unit.

e4b1fa69cd arch/arm: VFP and Thumb1 are not compatible
gcc will refuse to build with both --with-mode=thumb and --with-fpu=vfp,
with error messages during ./configure, like:

    checking for suffix of object files... configure: error: in `/home/ymor

    ux-uclibcgnueabihf/libgcc':
    configure: error: cannot compute suffix of object files: cannot compile
    See `config.log' for more details.

And config.log informatively contains:

    sorry, unimplemented: Thumb-1 hard-float VFP ABI

This is an error message that comes deep from gcc source files.

If gcc says it does not support VFP with Thumb1, then let's disable that
combination in our menuconfig.

Prefer VFP over Thumb1, i.e. hide Thumb1 when we're not soft-float.

1b171af3b3 arch: BINFMT_FLAT_SHARED is not really shared for buildroot purposes
Although BINFMT_FLAT_SHARED is indeed a shared library format, it does
not support dynamic library loading with dlopen(). So for buildroot
purposes, BR2_STATIC_LIBS shouldn't be selected.

As it happens, the compiler options that are added for
BINFMT_FLAT_SHARED also make the compiler ignore the -static option, so
we can simply force BR2_STATIC_LIBS and things work out perfectly.

Therefore, remove the select of BR2_BINFMT_SUPPORTS_SHARED from
BINFMT_FLAT_SHARED, which in turn makes sure that BR2_STATIC_LIBS is
selected.

Until now, all ARM processors supported the original ARM instructions.
However, the Cortex-M variants don't support them, and support only

So, make a Kconfig option for ARM support and use it.

  - Remove the dependency in the choice between ARM/Thumb/Thumb-2,
    because basically the choice is now always visible.
  - Replace the BR2_ARM_INSTRUCTIONS_ARM_CHOICE choice option directly

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.

[Thomas: remove useless empty newline right after 'choice'. Noticed by
Yann E. Morin.]

375c77ad4e arch: remove superfluous arch dependencies on BR2_BINFMT_FLAT_*
As noted by Yann E. Morin, those dependencies are unneeded, since FLAT
can anyway only be used on m68k and Blackfin.

b85837e5d6 arch: introduce BR2_BINFMT_SUPPORTS_SHARED
In preparation for the refactoring of the static/shared library
support, we add a BR2_BINFMT_SUPPORTS_SHARED hidden option that binary
formats supporting shared libraries should select.

c1a38829e7 arch: ensure BR2_BINFMT_ELF is really used
Currently, the binary format choice is only shown for the Blackfin and
m68k architectures, since we assume that all other architectures are
using the ELF binary format. However, due to this, the BR2_BINFMT_ELF
symbol is in fact not set to 'y' for those architectures that use the
ELF format.

This will be causing problems for the refactoring of the static/shared
library support, as we will need to know if the binary format supports
shared libraries or not.

Therefore, we simply make the choice visible on all architectures,
even if it means that on many architectures no other choice than ELF
will be available.

c149083f93 arch: FDPIC is not supported on m68k
The current binfmt selection in arch/Config.in allows to select FDPIC
on m68k, which is incorrect. This commit fixes that, and makes sure
FDPIC is the default on Blackfin, while FLAT is the default on m68k.

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.

cd88e49cd7 arch/powerpc: add fsl e5500 and e6500 support
Add Freescale E5500 and E6500 core support.
These can go in 32 or 64-bit mode.
I'm not aware of these being able to boot in LE mode so filter that out
until we get some feedback on it.
