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.
