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'
  ...
