Greetings! I'm pleased to announce that gcl/maxima is now supported in hppa, the last of the 11 Debian architectures. The issues were/are with gcc on this platform, and were masked somewhat by my not setting up gcl's internal compile flags correctly.
1) When compiling with -g, the final link fails, and explicitly asks for recompilation with -ffunction-sections. This works, and produces a maxima passing all tests. 2) Any optimization at all breaks the build. I have a gdb session/backtrace showing pointers not being passed correctly into functions if anyone is interested in looking into this. 3) I'm hoping some of these symptoms might ring a bell with knowledgeable hppa people, and that there may be some other combination of compliation flags which might enable optimization.
