* Bah. All this time gcc was linking programs against

Browse Source 
/usr/lib/crt1.o, while it should be using $glibc/lib/crt1.o.  This
  quick hack (prepending $glibc/lib to the GCC search path using "-B")
  fixes the problem, but a better solution to prevent this sort of
  thing is to remove these static paths from gcc.

  Note: this problem was found using the pure UML Nix environment
  (where we don't have /usr/lib).
