Intel-C: declare support for gnu11

Without extensions, functions like `strdup` are not available since they
are actually controlled by feature flags such as _SVID_SOURCE and
_BSD_SOURCE. When using `-std=c11` on Intel, none of these flags are
set, so the functions are not declared properly leading to compile
errors.
