These two macros print either a 16 digit hex number or an 8 digit
hex number. Unfortunately they depend on both target and host, which
means that the output for 32-bit targets may be either 8 or 16 hex
digits.
Replace them in most cases with code that prints a bfd_vma using
PRIx64. In some cases, deliberately lose the leading zeros.
This change some output, notably in base/offset fields of m68k
disassembly which I think looks better that way, and in error
messages. I've kept leading zeros in symbol dumps (objdump -t)
and in PE header dumps.
