* Add accidentally dropped armhf to architecture list * Add GDB debug package (Closes: #592512, #490049) * Provide GDB multiarch package (Closes: #610519) - Add gdb-multiarch package supporting extra bfd targets similarly to binutils-multiarch; the package is constructed much like gdb64 except that it's build with the gdb configure flags and --enable-targets=all for now. - Thanks Loïc Minier. * Fix conflicts between cross and regular gdb (Closes: #603347) - Pass --gdb-datadir=/usr/share/gdb-$triplet when building a cross-gdb and update gdb.install sed snippet to match; fixes conflict with gdb; - Thanks Loïc Minier.
