Subject: [PATCH] BaseTools: aarch64: add -fno-asynchronous-unwind-tables to gcc
cflags
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.
