Subject: Define _GNU_SOURCE at Makefile level

Provide the _GNU_SOURCE define at the CFLAGS, instead of repeating it in every
source.

* Makefile (CFLAGS): Add -D_GNU_SOURCE.
* lib.c (_GNU_SOURCE): Remove define.
* lnode.c (_GNU_SOURCE): Likewise.
* main.c (_GNU_SOURCE): Likewise.
* ncache.c (_GNU_SOURCE): Likewise.
* netfs.c (_GNU_SOURCE): Likewise.
* node.c (_GNU_SOURCE): Likewise.
* options.c (_GNU_SOURCE): Likewise.
* pattern.c (_GNU_SOURCE): Likewise.
* stow.c (_GNU_SOURCE): Likewise.
* ulfs.c (_GNU_SOURCE): Likewise.
* update.c (_GNU_SOURCE): Likewise.
