Details:

When attempting to build Octave with the GUI enabled using Homebrew, the build
fails for two reasons: 
    1) Qt is packaged as a framework, not a set of shared libraries.
    2) the framework is installed in /usr/local/Cellar/qt/4.8.5, not in the
system framework locations.

A simple patch to configure.ac, supplied here, can solve this first problem.
If you examine it, you'll see that it modifies the use of PKG-CONFIG on
darwin*) platforms so that it can grab not just the -L and -l linker
arguments, but the -F and -framework arguments as well, for QT_LDFLAGS and
QT_LIBS. I strove to design this patch so that it leaves non-Mac platforms
unaffected altogether, and still works for cases where Qt is made available
using libraries instead of frameworks.

However, this still fails, because libtool does not process -F properly, which
is necessary to address the second problem. I manually patched the libtool
that is generated by the configure script, and that patch is also included
here. However, because libtool is *generated* by configure, I do not know if
it is possible for this patch to be applied to the source at all.

I do understand that, in theory, Homebrew can just apply these patches during
the compilation process. I wanted to offer them here however in case you might
wish to ensure that this scenario can succeed without Homebrew.
