I tried on 3 boxes, and it seems to work on one of them. One thing I
noticed was that the box on which it worked, did not have the
CSWlibtool package installed, which means there was no
/opt/csw/bin/libtool (/opt/csw/bin is in PATH). The box on which it
worked, no libtool was available in PATH. I also noticed that the
lto-plugin directory is one of the two that provides its own libtool
executable. The other is zlib. As an experiment, I hand-edited the
generated Makefile in the lto-plugin directory, changing the default
LIBTOOL setting (pointing to ${topdir}/libtool) to /opt/csw/bin/bash
/opt/csw/bin/libtool.
It made the linking pass. But what would be the proper fix?

Same here.

Compilation breaks with:
This target does not support --with-arch.
Valid --with options are: cpu float tune
