Fixing the gcc-cross-wrapper; it failed after some changes related to breaking

dependencies with it. (I should never link ld.so with a NIX_LDFLAGS -rpath
forced)

I made vim, scummvm cross-build. I added prboom (that cross-builds).
Mplayer and elinks don't cross-build fine still, but are on the way.
The mplayer fails to build in a weird way; nix does not show either a gcc
error message or even the 'make' error message.
