SIGSTKSZ is constant while recent libcs started defining it as a
sysconf(...) call.

-    fflush: adjust to glibc 2.28 libio.h removal
-    
-    Problem reported by Daniel P. Berrangé in:
-    https://lists.gnu.org/r/bug-gnulib/2018-03/msg00000.html
-    * lib/fbufmode.c (fbufmode):
-    * lib/fflush.c (clear_ungetc_buffer_preserving_position)
-    (disable_seek_optimization, rpl_fflush):
-    * lib/fpending.c (__fpending):
-    * lib/fpurge.c (fpurge):
-    * lib/freadable.c (freadable):
-    * lib/freadahead.c (freadahead):
-    * lib/freading.c (freading):
-    * lib/freadptr.c (freadptr):
-    * lib/freadseek.c (freadptrinc):
-    * lib/fseeko.c (fseeko):
-    * lib/fseterr.c (fseterr):
-    * lib/fwritable.c (fwritable):
-    * lib/fwriting.c (fwriting):
-    Check _IO_EOF_SEEN instead of _IO_ftrylockfile.
-    * lib/stdio-impl.h (_IO_IN_BACKUP) [_IO_EOF_SEEN]:
-    Define if not already defined.
