    RISC-V: testsuite: fix an obvious build error
    
    For a non-multilib build, I see following errors.
    
    | FAIL: gcc.target/riscv/rvv/vtype-call-clobbered.c (test for excess errors)
    | Excess errors:
    | TC-INSTxyz/sysroot/usr/include/gnu/stubs.h:14:11: fatal error: gnu/stubs-lp64.h: No such file or directory compilation terminated.
    
    The test selects non default ABI lp64 (vs. lp64d) for no real reason.
    Fix that.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/riscv/rvv/vtype-call-clobbered.c: Fix -mabi.
