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.

     3 -= BEGIN original header =-

     4 ARMV5 can use STRD and LDRD access instructions but these accesses need to be 

     5 8 byte aligned. The dynamic linker's malloc needs to match this so structures

     6 become 8 byte aligned to void unaligned accesses.
