debug/gdb: install dependable libs in a generic target static libs dir

For now, ncurses is the only dependable target library built for gdb.
But expat is coming, and there's no reason to install each library in
its own place.

So, install ncurses in a generic directory, where other dependable
libraries can be installed as well.

     1 Applies to both glibc-2.2.5 and glibc-2.3.2, and probably glibc cvs as of Aug 2004.

     2 Needed to build glibc with linux kernels 2.4.23 or higher on ARM, 

     3 Fixes following error:
