In a gcc build script terminating with the instruction

I have suddenly started getting very many instances of both of
ld: /usr/src/debug/readline-8.2-2/terminal.c:nn various: undefined
reference to `{various}'
ld: /usr/src/debug/readline-8.2-2/display.c:nn various: undefined reference
to `{various}'
and the build fails.
The problem was with readline not gcc
and I assume originates in myarchive.a and the required switch -lreadline in
the gcc line
rather than in readline: nevertheless I reverted both libreadline-devel and
libreadline7
from 8.2-2 to 7.03 and the problem went away.
Please provide a few examples which include the actual texts of "nn various" and
`{various}' especially where any prefixes vary.
Did you also upgrade/downgrade libncurses-devel concurrent with
libreadline-devel as they are dependent?
Why suppress all warnings -w from the ld (or any) phase of compilation?
Those warnings could tell you what causes an issue.
