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.

In the conversion from choic to tristate, this got lost.

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.

61ebaa97ca cc/gcc: make sjlj config option a tristate 
A tristate fits better here than a choice.
