I filed the bug because, when we were setting up the ABI test baselines in
the first place, it seemed desirable to verify them against binaries built
from various past glibc versions (to check as far as possible that the
contents of each symbol version in the test expectations were the same as
the contents of that version in the corresponding glibc release), and
doing such verification showed up that symbol as having been accidentally
removed.
(I did remove the _q_* symbols from powerpc soft-float; those had, in
glibc 2.4, been accidentally added to version GLIBC_2.2, but had never
been usefully usable - and made the baseline there reflect the accidental
removal of __fe_nomask_env which had also never been usable for that
configuration.)
