"if so, this indicates problems in the libc."
So I suppose there is a problem with glibc.  We're running glibc 2.27
(from Fedora Rawhide).  What could be the problem?

You can look at the build log and Gnulib source to get an idea. For example, for fclose.o, gnulib/modules/fclose suggests that REPLACE_FCLOSE seems to be 1, and gnulib/m4/fclose.m4 says that it is 1 if either gl_cv_func_fflush_stdin ends in "yes" or if REPLACE_CLOSE is 1, and your log says "checking whether fflush works on input streams... no" so it sounds like this is the problem. Look in gnulib/m4/fflush.m4 to find the program that failed.

Similarly for the other .o files. Good luck.
