This isn't actually correct for all setups. For example, Linux
distribution packages sometimes use lib64/ instead of lib/. The same
could theoretically happen for include/. So if we started shipping
gmp.h, we should also create a new variable in base/build_h.jl so that
packages can reliably get the path to the include/ directory.
