gcc: fixed to install gdb plugin into the right place and not into $libdir

+Do not put gdb python plugin directly into $libdir
+
+Placing files like 'libstdc++.so.6.0.17-gdb.py' into '$libdir' results in
+warnings when running 'ldconfig' because it is not an ELF file.
+A common place where to put gdb plugins is '$datadir/gdb/auto-load$libdir'
+like '/usr/share/gdb/auto-load/usr/lib'.
+
+Note:
+
+This patch assumes that gdb and gcc are using the same prefix!
