RISC-V: Don't drop multilibs matching the default march/mabi

A multilib entry that shares march/mabi with the default may
differ in other options such as mcmodel, so it is not equivalent
to the default multilib.  Stop returning false for these entries
in riscv_multi_lib_info_t::parse so they are still recorded.

gcc/ChangeLog:

	* common/config/riscv/riscv-common.cc
	(riscv_multi_lib_info_t::parse): Remove early-out for multilibs
	matching only the default march/mabi.
