fix for darwin build problem

[Geoffrey Keating]

This should fix the reported problem building Darwin:

/Volumes/xufs/gccsrc/gcc/gcc/config/darwin.c:1291: gt-darwin.h: No
such file or directory

Tested on powerpc-eabisim, and I also checked that when building a
cross-compiler to Darwin, cc1 builds successfully.
