[DejaGnu] add dejagnu mips-sim-idt32 baseboard.

[cgd]

FYI, just checked this into the sources.redhat.com 'src' repository.
their maintainers file says to notify y'all about changes made there.

Also FYI, there was a change a few months ago (from Eric Christopher) to
add a mips-sim-idt64 baseboard, as well.  I dunno if you were notified
about it, but it doesn't appear in your current cvsweb so i thought
i'd mention it.

[ MAINTAINERS says to post dejagnu patches here... but doesn't say who
  approves them!  8-]


The following patch adds a mips-sim-idt32 baseboard, which is almost
identical to the existing mips-sim-idt64 baseboard.

The mips-sim-idt64 baseboard is used for mips64 testing, and sets the
ISA markings on the resulting binary to indicate mips64.

This new baseboard is for mips32 testing, and sets the ISA markings to
indicate mips32.

(If you're using a simulator that supports multiple ISAs, e.g. mips32
and mips64, and determines which to support via the binary ISA
markings, then using mips64 isn't The Right Thing: you don't catch
accidental use of mips64 instructions in the code being run.
Therefore, just using e.g. the -idt64 config isn't the right thing for
mips32.)


Once this is approved, i'll "Notify http://dejagnu.sourceforge.net/ of
generic changes." as suggested in the top-level MAINTAINERS file.
