52fcd86f2b uclibc: do not allow the selection of NPTL if snapshot is not selected
In uClibc, NPTL support does not exist in the 0.9.30 branch, that we
are using in Buildroot. It is only available in the uClibc daily
snapshot, extracted from uClibc master branch.

13e753b414 toolchain: select sensible floating point mode by default
Introduce BR2_PREFER_SOFT_FLOAT and enable it for arm, avr32 and mips,
and use it to enable soft float support by default for those archs.

This way people automatically get the correct floating point mode when
running make menuconfig for the first time (E.G. without a .config) and
changing the arch from i386 to arm/avr32/mips.

89b33886f7 toolchain: mark BR2_ENABLE_LOCALE_PREGENERATED as broken
There's still no suitable tarball available on uclibc.org, so better
hide the option for now.

8d880c3e5c Fix PROGRAM_INVOCATION handling with external toolchains
BR2_UCLIBC_PROGRAM_INVOCATION is a toolchain configuration option,
like BR2_INET_IPV6, BR2_INET_RPC, on which some packages
depend. Therefore, it should be handled like BR2_INET_IPV6 and
BR2_INET_RPC in order to work properly with external toolchains.

Since we move it out of toolchain/uClibc/Config.in into
toolchain/Config.in.2, we rename the option to BR2_PROGRAM_INVOCATION
(since BR2_INET_RPC and others don't have UCLIBC in their name).

27ce942e65 toolchain: Clean up locale support menu
Closes #421.

This patch cleans up and fixes some minor issues with the locale support
section of the toolchain menu.

1. uClibc requires wchar support if locales are enabled, make locale
   support select wchar support.

2.  Allow purging of locale information even if there is no locale
    support in the C library.  This cleans up after packages that
    install things into /usr/share/locale on the target.

b87b4742e0 Makefile: add BR2_ENABLE_LOCALE_PURGE to purge unwanted locales
Add BR2_ENABLE_LOCALE_PURGE / BR2_ENABLE_LOCALE_WHITELIST options to
remove unwanted locales from the target rootfs. Handy for stuff like
the gtk stack, which comes with ~25 MB locales.

Works similar to localepurge in Debian, E.G. you provide a white list
of wanted locales, and everything else is removed.

040bd64849 Extend External Toolchain options (match buildroot built toolchain):
Have added options that mean you can set the same BR2_XXXX variables
for external toolchain and internal (buildroot built) toolchain.

This means the same set of packages can be built now me as for you.....

6da70de503 The liboil Makefile will use "-mcpu=vfp" when building for ARM.
The VFP is only available for a few ARM CPUs at the moment,
so this breaks the liboil build.

A patch is available upstream which only enables "-mfpu=vfp"
if "--enable-vfp" is given to "configure".
Autotools needs to be run for liboil for this to take effect.

A new configuration BR2_VFP_FLOAT is added to allow enabling vfp.
If this is "yes", then "-mfpu=vfp" is added to CFLAGS.

e2e4950b2d toolchain: use same gdb Config.in for internal/external toolchains
We used to use different gdb configs for internal and external toolchains
because mconf won't source the same file twice. This works, but is kind of
sub optimal, as people forget to keep them in sync.

Fix it to use the same file for both situations by shuffling around the
config options a bit. Should work identical to before (except for the newer
gdb versions available for ext).

51f5f62754 External toolchain support improvements
Improve external toolchain support

 * Do not put kernel-headers in the dependencies of BASE_TARGETS in
   the case where BR2_TOOLCHAIN_SOURCE is not y. The kernel headers
   are already supposed to be part of the external toolchain, so
   there's no need to download, extract and install them.

 * In the configuration system, don't display the kernel headers
   version selection list when an external toolchain is selected. This
   is implemented by moving the source
   "toolchain/kernel-headers/Config.in" inside the if
   BR2_TOOLCHAIN_SOURCE in toolchain/Config.in.2.

 * Change the description and help message of the BR2_LARGEFILE,
   BR2_INET_IPV6, BR2_INET_RPC, and BR2_SOFT_FLOAT option in
   toolchain/external-toolchain/Config.in. In the case of an external
   toolchain, the semantic of these options is not to enable large
   file support, IPV6 or RPC (since the toolchain is already compiled,
   it has been decided previously). Their semantic is to let Buildroot
   know about the characteristics of the external toolchain being
   used.

   As an improvement, we could guess these values automatically:

    - for BR2_LARGEFILE, look at the value of __UCLIBC_HAS_LFS__ in
      bits/uClibc_config.h in the libc headers directory.

    - for BR2_INET_RPC, look at the value of __UCLIBC_HAS_RPC__ in the
      same file

    - for BR2_INET_IPV6, look at the value of __UCLIBC_HAS_IPV6__ in
      the same file

    - for BR2_SOFT_FLOAT, look at the output of $(CC) -v 2>&1 | grep
      -- "--with-float=soft"

   But I'm not sure how this would be possible, since these values are
   used at configuration-time by other configuration options, not only
   at build time.
