I believe that the OP's issue is that the collector HAS been tried with
that particular combination of machine and compiler.

Just not with that particular combination of *options*.

That's a gcc-ism; clang copied a lot gcc-isms.
I cannot find an analogue of that option in the cc manual page.

The likeliest problem is headers testing 'sparc' instead of '__sparc'.
Since sun and sparc are only defined when __sun and __sparc are, there
doesn't seem to be any point in ever testing for 'sun' or 'sparc';
they are "legacy" macros.
