[gcc r15-5799] aarch64: Fix build failure due to missing header

[Yury Khrustalev via Gcc-cvs]

aarch64: Fix build failure due to missing header

Including the "arm_acle.h" header in aarch64-unwind.h requires
stdint.h to be present and it may not be available during the
first stage of cross-compilation of GCC.

When cross-building GCC for the aarch64-none-linux-gnu target
(on any supporting host) using the 3-stage bootstrap build
process when we build native compiler from source, libgcc fails
to compile due to missing header that has not been installed yet.

This could be worked around but it's better to fix the issue.
