On the downside, the build process of stdenvLinux builds gcc 9 times
(3 x 3 bootstrap stages). That's a bit excessive.

/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).
