0917 on OpenServer ELF & libgloss query.

[Robert Lipe <robertl at dgii dot com>]

A fresh 0917 + Kean's OpenServer patches to make it multilibbed + Jason's
suggested workaround of turning off DWARF2 unwinding + my patch to shorten
section names for COFF.

'make bootstrap' worked nice and boring.

'make check' doesn't do what I'd guess it's sposta do.   It looks like
there is new code in libgloss.exp (function get_multilibs) that figures 
out if a compiler is multilibbed and if so, adds the multilib flags
(-mcoff) as a dimension of arguments in  the matrix passed to the compiler
under test.    I can't tell that code is ever called.   If I need to 
manually tell runtest about the multilibbing, I can't figure out the 
flags to do it.   If I just plain need to run runtest twice, once with
--tool_opts="-mcoff" then so be it.

Here are the interesting parts of the target ELF results:
