openssl: OpenSSL 3.2.0-alpha1: build failure on linux

Tried to build the alpha in conda-forge, ran into a build error on linux-64:

I’m leaving out how we point CC etc. to our compilers, set up CFLAGS etc., but can provide that if desired.

Interestingly, the build does not fail for linux on other arches (aarch64 / ppc64le), nor on other platforms.
