buildgcc: Drop libelf/elfutils

Looks like we were unnecessarily dragging this around for some time now.
GCC's installation manual doesn't mention libelf as a requirement and a
build of crossgcc-i386 doesn't show any sign of it being used.

This also fixes a lot issues on non-GNU distributions that were intro-
duced by switching to the elfutils version of libelf.
