With this patch, in theory you can create AArch64 exectuables from x86-64 object files, but that doesn't make sense and likely to crash the linker because we assume that all object files are uniform in terms of target types.

Sorry, I've never said that I want to generate an x86-64 executable from i386 object files. The `OUTPUT_ARCH` command doesn't do that anyway...
