Regarding the recent problems in sys/arch/i386/stand/mbr/Makefile.mbr that
arise because our /bin/sh doesn't want to properly convert a hex value
into a decimal value (" echo $(( 0xdeadbeef )) "), below's a possible
solution that uses nm(1) to do the conversion to dec.

Problem is that it uses sed(1) to strip leading zeroes, and I'm not sure
that's ok. At least there is no $(SED) macro defined, is it ok to use
sed(1) in that way? (Thinking about cross builds...)
