Indeed __GLIBC__ is only defined once a glibc header has been included,
and thus subsequently its features.h :
$ echo '' | gcc -dM -E -x c - -o - | grep \#define\ __G\\\(LIBC\\\|NU\\\)__
#define __GNU__ 1
$ echo '#include <stdio.h>' | gcc -dM -E -x c - -o - | grep \#define\
__G\\\(LIBC\\\|NU\\\)__
#define __GLIBC__ 2
#define __GNU__ 1
