[issue44096] Bad clang detection in configure script

[Rishav Kundu]

New submission from Rishav Kundu <rishav.kundu98 at gmail.com>:

Because autoconf detects `cc` before `clang` [1], this means that most of the checks in configure.ac that compare $CC to `clang` don’t work. This in turn means that things like LTO and PGO don’t work — the appropriate compiler options do not get set.

I can write a patch if someone can reproduce this.
