08ebd6ec3d cc/gcc: CC_STATIC_LIBSTDCXX 'depends on' CONFIGURE_has_static_libstdcpp
Hide the staticaly linked libstdc++ option if the static libstdc++ is not
present, detected at configure time.

Add a blind option that says whether static linking is possible at all.
It defaults to 'y', but depends on the needed CONFIGURE_* options. For
now, it only depends on static libtdc++, but new dependencies can be
easily added.

Hide the global static toolchain option behind this new option.

35fe8a047d gcc: promote PKGVERSION and BUGURL options to toolchain level
This patch promotes the PKGVERSION and BUGURL options to toolchain level so that
all toolchain components supporting them can benefit from them.

These options are passed to configure through --with-pkgversion and
--with-bugurl.

They are supported by binutils 2.18+, gcc 4.3+, eglibc 2.9+ and gdb 7.0+.

96245813d8 kconfig: remove useless 'default n'
kconfig bools are disabled by default, so specifying 'default n' is useless and
noisy. This patch removes all occurrences of 'default n'.

c4bb88466e config: rename variables that are arrays

It will be used later when .config gets munged to allow both multiple

67d96ea16f cc/gcc: cleanup the _or_later logic
So far, we've had a version always select appropriate _or_later option,
which in turn would select all previous _or_later options.

Because the dependencies on companion libs were cumulative, that was
working OK. But the upcoming 4.6 will no longer depend on libelf, so
we can't keep the cumulative scheme we've been using so far.

Have each release family select the corresponding dependencies, instead
of relying on selecting previous _or_later.

adbf0ff180 cc/gcc: enable plugins if needed

d34a5ec7d8 cc/gcc: do not force use of non-vital companion libraries
While GMP and MPFR are required by gcc>=4.3 (to build the frontends),
and MPC is required by gcc>=4.5, the other libs are not. If they are
present then gcc will enable advanced features; if they are missing,
then gcc will (should) simply disable those features.

143f02e0ce cc/gcc: add option to compile against static libstdc++, for gcc-4.4 and newer
Idea and know-how taken from CodeSourcery build script.

Normal build:
  $ ldd arm-unknown-linux-uclibcgnueabi-gcc
	linux-gate.so.1 =>  (0xb77f3000)
	libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb76e8000)
	libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb75a1000)
	libm.so.6 => /lib/i686/cmov/libm.so.6 (0xb757a000)
	/lib/ld-linux.so.2 (0xb77f4000)
	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb755c000)

CC_STATIC_LIBSTDCXX=y:
  $ ldd arm-unknown-linux-uclibcgnueabi-gcc
	linux-gate.so.1 =>  (0xb7843000)
	libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb76e6000)
	/lib/ld-linux.so.2 (0xb7844000)

I made CC_STATIC_LIBSTDCXX default=y since I think
it is always desirable.

8bb436dad1 cc/gcc: add option to enable/disable libmudflap
For some scenarii, libmudflap is not very usefull
or can break the build. Make in an optioon that
defaults to 'N' to be on the safe side.

For the core gcc-s, there is absolutely no need
to build libmidflap.
