This is on my custom OS that doesn't have gethostname ('hcos', which is in the
config.sub upstream). I am actually using newlib.
It seems like libgomp's configure.ac is already using AC_LINK_IFELSE for all
OS's around line 241 to 'Check for pthread_{,attr_}[sg]etaffinity_np.'.
In my newlib startup setup, I only build libgomp in stage2.
See here for Makefile:
https://github.com/riscv/riscv-gnu-toolchain/blob/master/Makefile.in
On line 541 I have --enable-threads and on line 551 I have --enable-libgomp
