GCC for 32-bit ARM chokes on .aslc files when running with LTO
enabled. Since LTO has no benefit whatsoever here, just disable
it.

Why not add it globally to GCC5_ASLCC_FLAGS?

There might be a special case for Aarch64, but I'm not seeing it.

I see IA32 and X64 arch both have this option. I have no idea on AArch64.
