OpenJDK 7 build fails on Snow Leopard

[Michael Franz]

Greg,

I think that _DARWIN_C_SOURCE needs to be included as well.  If not, the
pthread methods are not defined.

+  CFLAGS += -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE

I have successfully tested this on Leopard.  Snow Leopard builds but crashes
(this might be way I am building)
