We need this to be able to execute the resulting nxagent binary from
within the build directory.

nx-X11: build programs with a temporary RPATH/RUNPATH value and a relinked version with the system location.

While the install target explicitly installs the relinked
system-location version of a program, we do not actually use this.

Currently, we copy nxagent directly out of the build root.

As discussed in ArcticaProject/nx-libs#610, we need a way to load
libNX_X11 as a fake version of libX11 into nxagent's address space.

For doing so, we have to link against libX11 at build-time and specify
a(n) RPATH/RUNPATH to our libX11 -> libNX_X11 compat symlinks.

This commit is essentially doing a cross between options 3 and 4
discussed in the provided GH issue.

We link libX11 early (before specifying -Lcompat_symlinks_dir), so that
the linker finds the "real" libX11 version with the libX11 SONAME. This
leads to our binary depending upon both libX11 and libNX_X11 SONAMEs. We
already always added RPATH/RUNPATH, but these values are not passed down
to dependent libraries.

What happens at run-time is that the loader searches for a libX11
SONAME, takes RPATH/RUNPATH into account and loads our libNX_X11 library
instead via the compat symlinks. This satisfies the libX11 SONAME and
dependent libraries will *not* load the system libX11 version again.

Debian's dpkg-shlibdeps isn't quite happy about this mismatching SONAME
situation, so instruct to look the other way while we're minding our
business.

Fixes: ArcticaProject/nx-libs#610

We do not build loadable modules, so we do not need them anywhere.

Also remove the extra files requires for module builds.

 Fixes ArcticaProject/nx-libs#250.

Imake.rules: Make BuildIncludes{,Top}() more robust in case people attempt providing path names instead of file names via srclist.

Fixes ArcticaProject/nx-libs#223.
Fixes ArcticaProject/nx-libs#244.

library clean-up: Don't build and link libXfont.a anymore. Use system's libXfont shared library and link dynamically.

  We really want to make use of rpm's automatic dependency finding.
  Binaries are scanned for DT_NEEDED entries, the latter of which are
  then used for populating the "Requires"-type deps. The "nxagent"
  binary for example would require libX11.so.6. That incurs problems:

  1. A package manager told to install nxagent could select xorg-x11
  rather than nx-libs, even though nxagent depends on the NX version.

  2. A package manager told to install $some_program could select nx-libs
  rather than xorg-x11 (since both provide libX11.so.6), but, since
  the NX library is in an obscure directory, running $some_program
  would fail as libX11.so.6 is not found.

  To solve this, give the NX libraries unique names different from the
  Xorg ones.

This reverts commit e77bf36d.
