complibs: noone is using companion libs on the target; nuke them

As there's no longer any user of the companion libraries on the
target, nuke the build for the target.

Well, at least, there's libelf that's still needed by ltrace, so
we keep it.

     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.
