Regarding rpath, it looks like the quickest workaround is to hack the gcc specs file:
edit gcc/specs lines which reference link_arch*. Add -rpath-link /path/to/necessary/libs to each 
link_arch* line, right before -Y. Alternatively, if all you want to do is link standard 32 bit 
applications, you can just do this for link_arch_default. My link_arch_default looks something like 
this:

*link_arch_default:
%{G:-G}    %{YP,*}    %{R*}    %{compat-bsd:      %{!YP,*:%{p|pg:-rpath-link /tmp/dara/sparc-sun-
solaris2.8/sysroot/lib/ -Y P,/usr/ucblib:/usr/ccs/lib/libp:/usr/lib/libp:/usr/ccs/lib:/usr/lib}              
%{!p:%{!pg:-rpath-link /tmp/dara/sparc-sun-solaris2.8/sysroot/lib/ -Y P,/usr/ucblib:/usr/ccs/
lib:/usr/lib}}}              -R /usr/ucblib}    %{!compat-bsd:      %{!YP,*:%{p|pg:-rpath-link /tmp/dara/
sparc-sun-solaris2.8/sysroot/lib/ -Y P,/usr/ccs/lib/libp:/usr/lib/libp:/usr/ccs/lib:/usr/lib}              
%{!p:%{!pg: -rpath-link /tmp/dara/sparc-sun-solaris2.8/sysroot/lib/ -Y P,/usr/ccs/lib:/usr/lib}}}}

After doing this, you should no longer need to pass -Wl... Note that for 32bit and 64bit link_arch 
you _will_ need to specify different -rpath-link paths, since sparcv9 has its libs in the sparcv9 
subdirectory. Doing so I can successfully build a Linux x Solaris cross compiler that will build C 
and C++ programs (and said programs appear to run fine).
