25201bc9fe build-sys: allow a build when libdl.so is truly absent
The earlier commit purporting to allow top to be built
in the absence of that dynamic linking library stopped
just a little short of the truth. So this will fix it.

5686877cd4 build-sys: eliminate dependencies for the NUMA support
Oh that poor ol' build system. With this patch it will
have gone through three separate incarnations in terms
of NUMA/Node support. Those 3 iterations consisted of:

1. A 'porridge too hot' where the top numa support was
enabled if it was built in the presence of libnuma and
the numa.h header. But if the numa library wasn't part
of core packages, that would have broken poor old top.

2. A 'porridge too cold' where numa support was off by
default and must have been explicitly enabled when the
./configure script was run. This could have meant that
distros might not distribute a numa-aware procps, even
though their numa library would have been distributed.

3. And this 'porridge' where the top numa support will
become a 'plug-in' feature activated when the presence
of libnuma.so can be verified at runtime. We'll do our
own loading and symbol resolution (with some help from
dlopen in libdl). Thus maintainers' responsibility for
enabling numa support and then satisfying that library
dependency is now an entirely optional --disable-numa.

As Goldilocks might say about our current configure.ac
"Ummm, I think this porridge tastes just about right".

87ac6383bb build-sys: in top program, enable NUMA/Node extensions
This patch provides the build system support for those
top extensions dealing with the NUMA summary displays.

For providing the initial impetus for this enhancement
I wish to thank Lance Shelton <LShelton@fusionio.com>.

(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)

If stream status is not checked at the end of execution below problem
would not report error, or non-zero exit code.  The uptime is just an

3388f65c03 build-sys: correct all Makefile.am files for LOCALEDIR, etc
Some of the latest changes to Makefile.am files are missing.

This patch restores the LOCALEDIR variable, among others,
and dispenses with the include directives in the ps/ and top/
subdirectories since they're no longer needed.
