Can't build binutils with read-only source; Was: Linux GDB compilation problem

[Andrew Cagney <ac131313 at cygnus dot com>]

The below was sent to GDB@

As far as i can tell the analysis is correct.  A simple build shouldn't 
be trying to modify files in the ``read only'' src/opcodes tree.

enjoy,
Andrew
