[Bug 276170] LLVM bug prevents from enabling PGO optimization for Python 3.11+

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276170

--- Comment #30 from Guillaume Outters <guillaume-freebsd@outters.eu> ---
In reply to @Dimitri Andric about comment #25:

After having cleaned up my env, I could bissect the crash to a single:
export CC=clang
before running the configure.

Probably the configure chooses its profiling tool depending on the compiler's
declared name (at least before it inspects the default cc to determine it's a
clang).

I start from the original unmodified Python (not the ports patched one), at
http://www.python.org/ftp/python/3.13.1/Python-3.13.1.tar.xz
on a stock FreeBSD 14.1-RELEASE
with a minimalistic configure:
./configure --enable-optimizations
