Ah, I thought the caching was required to have config.status' --recheck
do the right thing. Which actually
As to the general case, I think float.h is probably the best choice
and stdarg.h probably just as good. It's been a very long time since
anything but GCC itself installed headers by those names.
For libc, I think always using $CC -E is fine. You don't need to bother

(That's the last one I'm currently seeing.) Again depending on
usability, we either get:
checking for [GCC] option to accept ISO C89... none needed
Or:

Also known as: »I found another one«.
As we already know, glibc's configure script is in a difficult position
in that it uses "standard Autoconf", but its tests shall not depend on
any functionality (for example, system headers) that is to be supplied by
the glibc we're about to build. In re
