In early buildroot, it apparently was customary to have following style in
Config.in files:
bool"expat"
Nowadays, only two packages remain with this style: diffutils and expat.
This trivial patch lines them up with the style:
bool "expat"

uClibc picks the wrong interpreter for MIPS64/n64.

With the move of uclibc to package/uclibc, the uclibc-menuconfig target now
depends on uclibc-configure, which brings in the build of
binutils/gcc-initial/mpfr/gmp, causing it to take ages with a clean tree.
Fix it by moving the basic .config mangling to the patch step, and depend
on that for menuconfig instead.
Notice that this is broken for _OVERRIDE_SRCDIR users, just like for
busybox, but as that is presumably a small subset of the buildroot
user base (and these advanced users can just run menuconfig in their
local uClibc tree), so this is considered the lesser evil of the two.
The proposed out-of-tree build series will also cause problems with
this.

This commit adds three patches to uClibc that are needed to make
Thumb2 support work properly:
uclibc-0006-arm-clone-restore-stack-pointer-just-after-return-fr.patch
uclibc-0007-arm-clone.S-Add-missing-IT-instruction-for-Thumb2.patch
uclibc-0008-arm-move-check-for-BX-to-its-own-header.patch
The first one is a necessary dependency of the second one. Both of
those patches have already been merged upstream, after 0.9.33.2. The

Until now, we were using the default ARM instruction set, as used by
the toolchain: the 32 bits ARM instruction set for the internal
backend, and for external toolchain, whatever default was chosen when
the toolchain was generated.
This commit adds support for the Thumb2 instruction set. To do so, it:
* provides a menuconfig choice between ARM and Thumb2. The choice is
only shown when Thumb2 is supported, i.e on ARMv7-A CPUs.
* passes the --with-mode={arm,thumb} option when building gcc in the
internal backend. This tells the compiler which type of
instructions it should generate.
* passes the m{arm,thumb} option in the external toolchain
wrapper. ARM and Thumb2 code can freely be mixed together, so the
fact that the C library has been built either ARM or Thumb2 and
that the rest of the code is built Thumb2 or ARM is not a problem.

This commit introduces the support for the EABIhf ABI, next to the
existing support we have for EABI and OABI (even though OABI support
is deprecated). EABIhf allows to improve performance of floating point
workload by using floating point registers to transfer floating point
arguments when calling functions, instead of using integer registers
to do, as is done in the 'softfp' floating point model of EABI.
In addition to this, this commit introduces a list of options for the
floating point support:
* Software floating point
* VFP
* VFPv3
* VFPv3-D16
* VFPv4
* VFPv4-D16
and it introduces some logic to make sure the options are only visible
when it makes sense, depending on the ARM core being selected. This is
however made complicated by the fact that certain VFP capabilities are
mandatory on some cores, but optional on some other cores. The kconfig
logic tries to achieve the following goals:
* Hide options that are definitely not possible.
* Use safe default values (i.e for Cortex-A5 and A7, the presence of
the VFPv4 unit is optional, so we default on software floating
point on these cores)..
* Show the available possibilities, even if some of them are not
necessarily working on a particular core (again, for the Cortex-A5
and A7 cores, there is no way of knowing whether the particular
variant used by the user has VFPv4 or not, so we select software
floating point by default, but still show VFP/VFPv3/VFPv4 options).
It is worth noting that this commit doesn't add support for all
possible -mfpu= values on ARM. We haven't added support for fpa, fpe2,
fpe3, maverick (those four are only used on very old ARM cores), for
vfpv3-fp16, vfpv3-d16-fp16, vfpv3xd, vfpv3xd-fp16, neon-fp16,
vfpv4-sp-d16. They can be added quite easily if needed thanks to the
new organization of the Config.in options.

Buildroot already has the BR2_GCC_TARGET_{TUNE,ARCH,ABI,CPU} hidden
kconfig strings that allow per-architecture Config.in files to feed
the appropriate values of --with-{tune,arch,abi-cpu} when building
gcc, or the appropriate flags for the external toolchain wrapper.
This commit has two additional options:
BR2_GCC_TARGET_{FPU,FLOAT_ABI}, that allows to define the
--with-{fpu,float} gcc configure options for the internal backend, or
the -m{fpu,float-abi} options for the flags of the external toolchain
wrapper.

When refactoring the internal toolchain backend logic, the code was
changed to pass the custom configure options given through
BR2_EXTRA_GCC_CONFIG_OPTIONS only for the gcc final pass, with the
idea that we're only interested by user customization for the final
compiler.
However, the beaglebone_defconfig was passing --with-float=hard
--with-fpu=vfpv3-d16 as BR2_EXTRA_GCC_CONFIG_OPTIONS, and since the
refactoring, it was causing build failures of the beaglebone_defconfig
(with messages saying that Busybox is built to use VFP arguments, but
libc/libm are not). This is due to the fact that the gcc intermediate,
which is used to build the C library, wasn't built to generate hard
float, while the final compiler was generating hard float.
So, we get back to the original situation where the options in
BR2_EXTRA_GCC_CONFIG_OPTIONS are passed to all of the compiler
passes. Of course, the specific case of hard float will be fixed by
following patches in this area, but the idea still remains: the three
gcc should have the same options, if those options affected the ABI of
the generated code.
