sys-libs/glibc: expose a knob to downgrade glibc
It's not something to be used lightly. Useful when the damage was not
yet done to the rest of the system.
Usage example:
# I_ALLOW_TO_BREAK_MY_SYSTEM=yes emerge -v1 "=glibc-${old-version}"
Be prepared to deal with downgrade consequences like disappeared symbols
and versions of symbols
Package-Manager: Portage-2.3.69, Repoman-2.3.16
