Clean up compilation warnings coming from PL/Perl with clang-12~
clang-12 has introduced -Wcompound-token-split-by-macro, that is causinga large amount of warnings when building PL/Perl because of itsinteractions with upstream Perl. This commit adds one -Wno to CFLAGS at./configure time if the flag is supported by the compiler to silence allthose warnings.This back-patches commit9ff47ea into out-of-support branches,pursuant to newly-established project policy. The point is tosuppress scary-looking warnings so that people building thesebranches needn't expend brain cells verifying that it's safeto ignore the warnings.Discussion:https://postgr.es/m/d0316012-ece7-7b7e-2d36-9c38cb77cb3b@enterprisedb.com
