The current relative path to libquadmath can be incorrectly interpreted
on systems that hard code library paths.  In particular, on 32-bit
hppa*-*hpux*, the '..' part of the path is relative to the final executable.
As a result, all libgfortran tests fail due to a dynamic loader error.

The patch changes the path to an absolute path.

Tested on hppa2.0w-hp-hpux11.11 and i686-apple-darwin9 with no observed
regressions.

OK for trunk?
