+Subject: [PATCH] riscv: Make contribs build again.
+
+The issue was that the LINKAGE_TEMP_REG being NL3 was a C argument
+register, so of course that caused clashing on C call-out, causing
+problems with run-program. Going back to NL7 didn't work either
+because it wasn't getting saved before entry into the trampoline. The
+code here used to have NL7 before the trampoline code was gutted and
+then restored, so I'm wondering how this ever worked before, because
+it definitely did. Pick LIP as the TEMP_REG now because not only does
+it get saved, it's also the least likely thing to get disturbed by
+clobbering.
+
+Fixes #lp2002930.
+
+Also remove assembly routine printing because it doesn't need to be
+part of the build script (unlike the other files in output/ which
+can't trivially be recovered from a built image), and because not all
+disassembler printers have been written on riscv yet.

Thanks. I wasn't looking forward to having to fix this one myself.
Patch pushed!
