partitions: dos: improve guess of disk size

The code used to ineffectively take the end of the last partition as guess
for the disk size. Better use the end of the partition that has its end
rearmost.

Also return an unsigned type instead of int as the result is always
non-negative.

scripts/setupmbr: fix documentation

The documentation says setupmbr should be used with the image named
'barebox', but it should instead be done with the 'barebox.bin'
image. Attempting to use setupmbr on the ELF barebox image simply
fails:

$ ./scripts/setupmbr/setupmbr -s 32 -m ./barebox -d disk.img
No MBR signature found
barebox image seems not valid: Bad MBR signature

arch/x86: fix link with recent gcc

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.
