Proposed PATCH ARM -- minor cleanup & revert arch_mach comparing code

[Richard Earnshaw <rearnsha at arm dot com>]

As mentioned yesterday, the iwmmx patch introduced a problem that 
prevented any linking between code compiled for different ARM 
architectures; and worse was marking files incorrectly and with internal 
bfd enumeration values.  This patch reverts those bits of code and in 
addition does some minor tidying up on the placement of the wmmx 
instructions in the opcode table.

This fixes building a gcc+binutils+newlib tree for arm-elf.

R.
