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.

I can confirm that this patch fixes my problem. The machine is a native AArch64 server, with Fedora GCC 4.8.3.
