[Polyml] Re: Weird error with polyc on Fedora 41 under UTM on Apple Silicon

* Jerry James:

I maintain the Fedora polyml package. All Fedora packages are built with a standard set of flags, including "-specs=/usr/lib/rpm/redhat/redhat-annobin-cc1" to build binaries with annobin (https://sourceware.org/annobin/). The polyml build stashes the flags that were used to build polyml itself into polyc; see the CFLAGS definition. I could use some guidance here. We can do one of two things.

There's a variant of %build_cflags called %extension_cflags. It contains just flags that can be hard-coded into build tools because they do not have dependencies on separate files. It would have to be used in addition to polyml's own defaults (which presumably includes -O2 -g at least), unlike %build_cflags.
