I'm trying to load a module built on recent illumos on a pretty older system and getting: undefined symbol __x86_indirect_thunk_r{a,b,c}x, is there a way get rid of these symbols (like I did with STACKPROTECT=none)?

I think they come from -mindirect-branch=thunk-extern and -mindirect-branch-register

So perhaps patch those out of usr/src/uts/Makefile.uts on the build system

andyf: that did it, thanks! (looked there, but somehow failed my search)
