Sure.

Note however, that xml descriptions can also send
the OSABI.  So if we had new xml descriptions that
did something like:

<!DOCTYPE target SYSTEM "gdb-target.dtd">
<target>
  <osabi>Lynx178 (or whatever it is)</osabi>
  <xi:include href="..."/>
</target>

and send _that_, then GDB sets the OSABI from
the target, even if you attach without a binary.
This is the modern version of the default OSABI
setting in the end of gdb/configure.tgt, which
I now notice doesn't have a Lynx setting, so
ignore I mentioned it.  :-)
