[PATCH 07/08] Generalize Makefile .so Version
Against: numactl-2.0.3-rc2
When building "upstream" libnuma on a system with, e.g., a distro-supplied
numactl package installed, I find it useful to build a different version of
libnuma.so, so that both versions of the library can co-exist.
This patch replaces all explicit usage of the libnuma.so.N file name with
the make variable LIBNUMA_SO.
Note that I'm building with 'libnuma.so.2'. I think this makes sense for
numactl 2.x.y, but may not be what you want.
