Some AArch64 tests force -mbig-endian and indirectly include stdint.h.
However, not all OSes support both endiannesses, leading to:
FAIL: gcc.target/aarch64/advsimd-intrinsics/bf16_get-be.c -O0 (test for
excess errors)

UNRESOLVED: gcc.target/aarch64/advsimd-intrinsics/bf16_get-be.c -O1
check-function-bodies test_vget_low_bf16
etc. This patch adds an (admittedly special-purpose) target
selector for this.
Tested on aarch64-linux-gnu. It doesn't really count as AArch64-specific
so: OK to install?
