Yep, I recall other sparc platforms suffering from the same issue.

More or less, yes.

What I actually did was to concat several solaris headers and started to
comment out everything that seemed solaris specific or unnecessary for
RTEMS. 

Unfortunately, I don't recall all details of hand and would have to look
into the patch again (this all happened several months ago and the
feedback on it wasn't necessarily encouraging enough to continue this
work :( ).

May-be, I'd have to check the details, but ... currently don't have the
time for checking it. I'd expect all sparc/ELF ports to share a common
(non-solaris/non-linux/elf-only specific) file.
