[runtime] Disable KMP_HAVE_QUAD on NetBSD gcc
Disable KMP_HAVE_QUAD when building via gcc on NetBSD system,
as the build fails due to unimplemented builtins:
.../kmp_atomic.cpp.o: In function `__kmpc_atomic_cmplx16_mul':
.../kmp_atomic.cpp:1332: undefined reference to `__multc3'
.../kmp_atomic.cpp.o: In function `__kmpc_atomic_cmplx16_div':
.../kmp_atomic.cpp:1334: undefined reference to `__divtc3'
...
