libnss: add build workaround for older gcc versions

Browse Source 
nss uses some #pragma directives that require newish (>= 4.6) versions
of gcc, so disable Werror when building with older versions to avoid the
build from breaking unfairly.
However make this a gcc >= 4.8 conditional since the kludge is called so
(NSS_NO_GCC48) and other bits might depend upon it.
