[PATCH v1 1/1] aarch64: Fix big-endian testsuite on little-endian hosts

[Karl Meakin via Sourceware Forge]

From: Karl Meakin <karlwfmea...@gmail.com>

On little-endian hosts, gcc with `-mbig-endian` only works if hosts have
`/usr/include/gnu/stubs-lp64_be.h` installed. So the call to `dg-runtest` should
have been guarded by a check for that support.

gcc/testsuite/ChangeLog:

        * gcc.target/aarch64/neon/aarch64-neon.exp: Guard call to
        `dg-runtest` with
        `check_effective_target_stdint_types_mbig_endian`.
