No, x264 thinking it does not have them, while they are actually available is
problematic (I don't know if it is causing any real issues, but it is wrong).

Look at the error closely:

 >> conftest.c: In function 'main':
 >> conftest.c:2:24: error: ignoring return value of 'malloc', declared with attrib
 >> cc1: all warnings being treated as errors

So the problem is that -Wall -Werror somehow is in the CFLAGS when the tests run,
causing the test to fail (where it should succeed)

Fix the test code, changing it to something like:

void *p; p = gf_malloc(1); gf_free(p);
