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

Can you specify the exact configure flags you used, and the exact make
command(s)?  I have tried here with v3.13.1 on 15-CURRENT with clang 19.1.5,
and:

CC=cc CXX=c++ /share/dim/src/python/cpython/configure --enable-optimizations
gmake -j12 V=1

and it works just fine. I don't see any specific PGO options passed to the
compiler invocations in the "Rebuilding with profile guided optimizations"
part, though.

So for some reason it might not always do this, even with the
--enable-optimizations configure option?
