I need a few wrapper programs to link statically against libstdc++ (or
libsup++). It is part of the specification that they may run on a system
where is not present.

Yes, that's what I have in mind. If I use <find-static-library>, I
expect it to fail if there's no libwhatever.a. In fact, -Bstatic is
linker-specific, not platform-specific. That is also the case for
"-Wl,-R", "-Wl,-h", "-Wl,-rpath-link" and "-Wl,--strip-all". I'm
updating my BB setup and haven't got to solaris yet but I believe
--strip-all is going to cause problems. -rpath-link is also potentialy
problematic but I'm not using it so it's not a biggie.

Perhaps we could configure gcc.jam to use a specific set of linker
options, like:

using gcc : 3.3 : <linker>sun ;

I'll try that.
