[PATCH] top: add the major version to dlopen of libnuma soname
- From: Jim Warner <james.warner@xxxxxxxxxxx>

When the plug-in approach to NUMA support was added, I
carelessly employed the compile-time linker convention
for naming the library. Technically this then required
the 'devel' package for NUMA support to be present for
the unqualified soname symlink to be available. Either
that or one must have manually created such a symlink.
This commit adds the missing major version to dlopen()
of libnuma.so.1 so simply having a more likely package
such as 'numactl' will enable both '2' & '3' commands.
