Move the threading model choice back to the C library menu:
- the threading models available are dependent on the C library used
- it is thus easier to first select the C libary, and then the threading model, rather going back to the toolchain menu.

     1 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.0/gentoo/53_all_gcc4-superh-default-multilib.patch

     2 The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,

     3 you have to actually list out the multilibs you want or you will end up with

     4 just one when using targets like 'sh4-linux-gnu'.

     5 

     6 The resulting toolchain can't even build a kernel as the kernel needs to build

     7 with the nofpu flag to be sure that no fpu ops are generated.

     8 

     9 Here we restore the gcc-3.x behavior; the additional overhead of building all

    10 of these multilibs by default is negligible.
