Hello.

These are changes to GDB 4.7 in order to support it for
BSD/386 from BSDI. Unfortunately, because BSDI uses a new
a.out format (magic number 0314) it is kind of difficult to
merge it into the 386BSD support without pain. So these
changes adds the configuration option 'i386-unknown-bsdi'

First are a set of context diffs, followed by a set of
new files in a shell archive.
