? If so, then I think Olivier should review it and then just go ahead and commit it, preferably with:
Tested-by: Wei Huang wei@redhat.com
based on Wei's message with Message-Id 54F740B4.3050104@redhat.com.
Unfortunately I can't find that email at the moment in the gmane archive, but I'm attaching it.
Thanks Laszlo

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

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.

Ping -- a colleague of mine has just run into this. (I don't use Fedora, but many of my colleagues do.)
