Add files to enable compiling for ARM native/cross builds.
This can be tested by doing a cross-compile for armv8-a type using
the linaro gcc toolchain.
meson arm-build --cross-file aarch64_cross.txt
ninja -C arm-build
where aarch64_cross.txt contained the following
[binaries]
c = 'aarch64-linux-gnu-gcc'
cpp = 'aarch64-linux-gnu-cpp'
ar = 'aarch64-linux-gnu-ar'
[host_machine]
system = 'linux'
cpu_family = 'aarch64'
cpu = 'armv8-a'
endian = 'little'
