Centralizes the definition of _GNU_SOURCE into lib.mk and addresses all resulting macro redefinition warnings.
The initial attempt at this patch was abandoned because it affected lines in many source files and caused a large amount of churn. However, from earlier discussions, centralizing _GNU_SOURCE is still desireable. This attempt limits the changes to 1 source file and 14 Makefiles.
This is condensed into a single commit to avoid redefinition warnings from partial merges.

Centralize the _GNU_SOURCE definition to CFLAGS in lib.mk. Remove redundant defines from Makefiles that import lib.mk. Convert any usage of "#define _GNU_SOURCE 1" to "#define _GNU_SOURCE".
This uses the form "-D_GNU_SOURCE=", which is equivalent to "#define _GNU_SOURCE".
Otherwise using "-D_GNU_SOURCE" is equivalent to "-D_GNU_SOURCE=1" and "#define _GNU_SOURCE 1", which is less commonly seen in source code and would require many changes in selftests to avoid redefinition warnings.

Andrew,
I am seeing merge conflicts with mm and exec tests. Might be better to have you take this through your tree?
