[PATCH] RISC-V: Update testcase.

[Kito Cheng]

From: Kito Cheng <kito.cheng@gmail.com>

gcc.target/riscv/arch-1.c getting failed after r269586, because it
wrapping all option names in gcc internal messages with %< and %>,
it make option name will print with single quote, and then mis-match
the result in the test case.

gcc/testsuite:
