Since #134923 / PR #134924 clangcl PGO builds on Windows fail with

lld-link : error : could not open '/GENPROFILE': no such file or directory [e:\cpython_clang\PCbuild\pythoncore.vcxproj]

I thought about skipping news, but since this also affects 3.14, I should blurb it?

@zooba WDYT? Can you suggest something that's not too verbose?
