these work for !arc targets. disabling them for all targets because they
are broken on arc seem weird even if they might not be used.
rather than cluttering the makefile how about marking the packahe broken
for arc and adding a new one called gdb-arc that depends on arc only.
this will allow us to keep gdb clean and just drop the gdb-arc package
once the fixes treacled down the tree.
