Using check_cflags with -Werror parameters in clang is normally
futile, since the tests always pass, but add new warnings instead.
Since the check for -Werror=partial-availability is in the OS section
of configure, we need to try adding this option here as well, not
in the section adding other warning flags later.
This fixes warnings about -Werror=partial-availability being unknown
for each compile command, when building with Xcode 6.

Or should this be in an OS-independent step before the whole OS handling
block in configure, making sure that cflags checks work as intended for
clang, anywhere in the rest of configure?
