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.

     3 I tried to use crosstool-ng to generate a toolchain for Linux on big

     4 endian arm with recent versions of gcc, glibc, etc... but had a few

     5 problems.

     7 It appears that the gcc patch (for gcc 4.2.x)

     8 for big-endian arm (240-arm-bigendian.patch) lacks the change attached

     9 to this mail as 240-arm-bigendian2.patch.
