buildtools: move to working directory

There is absolutely *no* reason for the buildtools (wrappers to gcc, g++,
as, ld... for the local machine) to be in the toolchain directory. Moreover,
they are removed after the build completes.

Move them out of the toolchain directory, and into the build directory (but
yet the part specific to the current toolchain). This means we no longer
need to explicitly remove them either, BTW, but we need to save/restore them
for the restart feature.

     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.
