[Gary Oberbrunner]

Try using $TEMPFILE.  MSVC uses it for this purpose.  Start by wrapping the
LINKCOM with TEMPFILE like ${TEMPFILE('$LINK ...')} and then maybe set
$TEMPFILE to TempFileMunge, and check Platform/__init__.py for how
TempFileMunge works; you'll need to make it use the --via or whatever your
linker needs.  If you come up with something useful, at least post it on
the wiki, or make an add-on tool that people can use (e.g. by putting it in
site_scons/tools).
