bochs/bios: Fix build

Currently, this project does not build on Ubuntu. "make" fails in the
bochs/bios/ directory with the following error:

 ld -o rombios32.out -T ./rombios32.ld rombios32start.o rombios32.o
 ld: section .eh_frame loaded at [00000000000e3e40,00000000000e453f]
  overlaps section .data loaded at [00000000000e3e40,00000000000e3e43]
 make[1]: *** [rombios32.out] Error 1

Build environment:

 - Ubuntu 14.04 x86_64
 - gcc (Ubuntu 4.8.4-2ubuntu1~14.04) 4.8.4
 - GNU ld (GNU Binutils for Ubuntu) 2.24

Back-porting the following patch from the upstream Bochs codebase fixes
this issue:
