At the moment, it's not possible to set pending breakpoint
via MI. This patch fixed it. Now if one does

	-break-insert -f symbol_in_shared_lib

GDB will create a pending breakpoint if symbol_in_shared_lib
is not yet seen. The -f stands for "future". We can't use -p
since that grabbed by thread option (which cannot be -t since that's
grabbed by temporary option). Apple branch uses -f as well,
as we might as well be compatible (even if the code is completely different).

OK?
