include/features.h: add _DEFAULT_SOURCE macro
man feature_test_macros(7) specifies that _BSD_SOURCE and _SVID_SOURCE have been deprecated in favor of _DEFAULT_SOURCE since libc 2.20. Specifying either of the former is now equivalent to specifying just the latter. We add this macro to conform to this standard, but do not add the compiler warning to maintain full backwards compatibility with earlier version of glibc and uclibc. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
