For RISC-V linux/glibc toolchain will got header file not found when including
stdint.h if multilib is not enabled, it because some header file will
try to include gnu/stubs-<ABI-NAME>.h from the system, however it only
generated when multilib enabled.
In order to prevent that, we introduce a wrapper for riscv_vector.h,
include stdint-gcc.h rather than the default stdint.h.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/base/riscv_vector.h: New.
