ntpsec: Add -D_GNU_SOURCE and fix building with devtool

wscript detects .git directory and if its present them invokes git
describe --dirty which does not work on the devtool created git
repository, since its synthesized.

Add GNU_SOURCE define to get strptime() definition

+Subject: [PATCH] wscript: Widen the search for tags
+
+Default is to look for annotated tags, howveer when using devtool we
+create our own git tree from release tarballs which will have tags but
+they are not annotated, therefore broaden the search to include all tags

+Upstream-Status: Inappropriate [OE-specific]
