cc-gcc: the frontends are responsible for mkdir/chdir

The build dir are created depending on the host (host for that specific
backend, not host for the toolchain). Only the frontends know what host
this is, so only the frontends can create non-ambiguous dirs.

     5 The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
     6 you have to actually list out the multilibs you want or you will end up with
     7 just one when using targets like 'sh4-linux-gnu'.
     8 
     9 The resulting toolchain can't even build a kernel as the kernel needs to build
    10 with the nofpu flag to be sure that no fpu ops are generated.
    11 
    12 Here we restore the gcc-3.x behavior; the additional overhead of building all
    13 of these multilibs by default is negligible.
