Don't rely on questionable impact of DT_RPATH on dlopen().
This is a bit of a messy subject, but probably the clearest
reference to motivate *not* relying on how dlopen() behaves
in the presence of RPATH or RUNPATH is the following:
https://sourceware.org/ml/libc-hacker/2002-11/msg00011.html
FWIW the dlopen() manpage only mentions the the RPATH
and RUNPATH in the "executable file for the calling program";
no mention of the executable files for libraries--
this has been brought to the attention of the relevant
parties and AFAICT nothing has been done.
The best reference for glibc behavior is
apparently to ... "try it and see".
Luckily a generous soul did exactly that
and reported the findings:
https://www.spinics.net/lists/linux-man/msg02291.html
Qt wrote on the subject a bit when they were bit by this,
linking to the above articles (directly or indirectly).
See:
http://blog.qt.io/blog/2011/10/28/rpath-and-runpath/
--------
Since we know the path of libGL at build-time for libepoxy,
there's a simple solution we can use to avoid all of this:
simply teach libepoxy to explicitly look in the libGL path.
This commit patches libepoxy to accomplish this,
looking to "LIBGL_PATH" as a fallback if it cannot find
the libraries otherwise.
---------
This fixes use of libepoxy w/musl on NixOS!

This is only needed if built from the source repository, since we are
using the release tarball the generated manpage is included. This
removes the "wild" dependency on ruby very deep in the dependency tree.

So far, `mkValueString` defaulted to `toString`,
which is a bad match for most configuration file formats,
especially because how booleans are formatted.
This also improves error messages for unsupported types.
Add a test to codify the formatting.
