[PATCH] RISC-V: testsuite: Do not set default arch for RVV.

[Robin Dapp]

Hi,

as per recent discussion and in order to fix inconsistencies
between spike and qemu this patch removes gcc_march and gcc_mabi
arguments from the default CFLAGS in the testsuite invocation for
some sub directories.

Juzhe reported that this helps for him.

Regards
 Robin

        * gcc.target/riscv/rvv/rvv.exp:  Remove -march and -mabi from
        default CFLAGS.
