It looks like Rich is hitting a similar problem when trying to test 
gnulib on RISC-V:

https://fedorapeople.org/groups/risc-v/logs/lbzip2-2.5-8.fc27.src.rpm/build.log


gcc -DHAVE_CONFIG_H -I.     -O2 -g -pipe -Wall -Werror=format-security 
-Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions 
-fstack-protector-strong -grecord-gcc-switches 
-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1  -c -o printf-args.o 
printf-args.c
fseterr.c: In function 'fseterr':
fseterr.c:77:3: error: #error "Please port gnulib fseterr.c to your 
platform! Look at the definitions of ferror and clearerr on your system, 
then report this to bug-gnulib."
  #error "Please port gnulib fseterr.c to your platform! Look at the 
definitions of ferror and clearerr on your system, then report this to 
bug-gnulib."
   ^~~~~
make[3]: *** [Makefile:1474: fseterr.o] Error 1

where I suspect the real problem is that the glibc header changes have 
interfered with what fseterr.c used to rely on.
