That's odd. As far as I can see, lib/assert.h is needed only if you need 
to compile lib/filevercmp.c, lib/nanosleep.c, lib/pipe2.c, 
lib/rawmemchr.c, or lib/strtoimax.c, and I don't see why choosing clang 
over gcc would affect whether these files need to be compiled.

I didn't notice the problem partly because I tested on Fedora 36, where 
none of the above files need to be compiled. Anyway, it is indeed a 
glitch on some platforms and I installed the attached patch to fix the 
annoyance. Thanks for reporting it.
