With digital signature verification support (SIGNATURE, MPILIB) enabled
on the Alpha platform, I get the following during the MODPOST section of
the build:
ERROR: "__udiv_qrnnd" [lib/mpi/mpi.ko] undefined!
Current compiler is gcc-4.6.3

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.
