Fix bochs build with gcc 4.6.0.
    
    A warning was being generated that looked like:
    
    ld -o rombios32.out -T ./rombios32.ld rombios32start.o rombios32.o
    ld: section .eh_frame loaded at [00000000000e3474,00000000000e3a73] overlaps section .data loaded at [00000000000e3474,00000000000e347f]
    
    The solution is to patch the rombios32.ld file to strip out the
    .eh_frame section, which shouldn't be needed in the BIOS.
