libgomp: Fix allocator handling for Linux when libnuma is not available
Follow up to r14-2462-g450b05ce54d3f0. The case that libnuma was not
available at runtime was not properly handled; now it falls back to
the normal malloc.
libgomp/
* allocator.c (omp_init_allocator): Check whether symbol from
dlopened libnuma is available before using libnuma for
allocations.
