Some toolchains, at least Fedora GCC, generate inline unwind tables in
object files. These confuses GenFw to no end, leading to build failures:
  GenFw: ERROR 3000: Invalid WriteSections64(): ...
         unsupported ELF EM_AARCH64 relocation 0x105.
  GenFw: ERROR 3000: Invalid WriteSections64(): ...
         unsupported ELF EM_AARCH64 relocation 0x0.

I am aware of no current use of these tables, so explicitly disable
their generation for aarch64.
