It built fine for me.

Are you on 15.0 or current?  Perusing through the system headers I saw
some comment that SIGSTKSZ was being redefined from a constant to
something potentially variable in glibc >= 2.34.  So if you're on
current with glibc 2.35, you may be getting a build failure that is not
reproducible on 15.0.
