Without that patch cross-compiling kernel for omap2 devices on BSD-style
hosts is broken.
For x86 targets the impact is not that hard but CFI is omitted even
though it is supported by assembler (in one case this led to a devious
error message pointing to a assembler bug in my cross toolchain).

So please consider applying this patch.
