[PATCH 2/2] arch/x86: fix link with recent gcc

[Thomas Petazzoni]

Due to unwind tables being generated by recent versions of gcc by
default, the x86 Barebox link fails with:

ld: section .eh_frame loaded at [00000000000197c4,000000000001f31f]
overlaps section .barebox_initcalls loaded at [00000000000197c4,0000000000019833]

Passing -fno-unwind-tables -fno-asynchronous-unwind-tables avoids this
problem.
