Got a workaround. I'll leave it to the "powers that be" for a proper fix. Issue is "__udiv_qrnnd" is part of "arch/alpha/math-emu" and is built-in. If MPILIB is built as a module, you get the undefined symbol error. If "CONFIG_MPILIB=y" (built-in), no undefined symbol issue.
My best guess is, the proper solution will involve either tightening the configuration dependencies a bit, or making sure required symbols are properly exported for use by modules.
