libgomp has a directory hierarchy that allows overriding
generic implementations of some parts with other implementations
for selected targets, e.g. the generic implementation can be
a fallback and the specific doing something more advanced.

For affinity, libgomp/affinity.c is such a fallback implementation
that doesn't do anything useful, and libgomp/config/linux/affinity.c
is a Linux specific implementation.

I think for libgompd you want something similar, doesn't necessarily
need to be a *.c file, could be just ompd-affinity.h which is
overridden by config/linux/ompd-affinity.h.
