[PATCH] RISC-V: Tweak the wording for the sorry message

[PATCH] RISC-V: Tweak the wording for the sorry message

[Kito Cheng]

Use "does not" rather than "cannot", because it's implementation issue.

gcc/ChangeLog:

	* config/riscv/riscv.cc (riscv_override_options_internal): Tweak
	sorry message.

Thanks, but don't you have to update the tests too, at least
gcc/testsuite/gcc.target/riscv/rvv/base/big_endian-2.c ?

thanks

I think zvl_unimplemented-1.c and zvl_unimplemented-2.c should also be fixed.
