hub - r30629 - in abiword/trunk: configure.in src/Makefile.am

I admit that I don't know much about the build system, but there are some
changes in the patch from Mageia that break building AbiWord on my PC. I get
errors like

  make[3]: *** No rule to make target `-lfribidi', needed by `libabiword-2.9.la'. Stop.

and

 ld: cannot find -lfribidi

This library (as libwv) is stored in a directory different from the system
libs, but accessible through pkgconfig information which worked fine so far.

The attached patch fixes my build problems, but I don't know whether it might
cause other troubles. If it doesn't I will apply.
