The overall intent of this patchset is to support long symbol names in
MODVERSIONS, needed for Rust support and some LTO contexts.

Only update here is to fix the PPC dot munging code since I haven't
heard anything else back yet. My understanding is that I primarily need
feedback from Luis based on his response to the original series [1] and
response [2] to the hash approach.

Full context is available in the previous cover letter [3].
