Build: Define feature test macro _DEFAULT_SOURCE

This basically makes glibc expose the same set of features as
if gcc was invoked without any restricting -std=c* option. Unlike
_GNU_SOURCE however, it does not enable GNU-specific extensions.

So, with this macro defined the behavior of Linux with glibc
should match that of other platforms.
