scripts: on startup, also remove the buildtools dir

In case there's one lingering around (whether the previous build was
successful, or failed), we have to remove the buildtools directory
as well as the toochain build dir.

This should also fix the case where out makeinfo wrapper calls
itself recursively.

     4 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch

     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.
