This appears to have broken glibc build on s390:

LANGUAGE=C LC_ALL=C makeinfo -P /home/andreas/glibc/glibc-build/manual/
--output=/home/andreas/glibc/glibc-build/manual/libc.info libc.texinfo
/home/andreas/glibc/glibc/manual//contrib.texi:1: Prev reference to nonexistent node
`Platform' (perhaps incorrect sectioning?).
/home/andreas/glibc/glibc/manual//maint.texi:1: Next reference to nonexistent node
`Platform' (perhaps incorrect sectioning?).
makeinfo: Removing output file `/home/andreas/glibc/glibc-build/manual/libc.info' due to
errors; use --force to preserve.
make[2]: *** [/home/andreas/glibc/glibc-build/manual/libc.info] Error 1
make[2]: Leaving directory `/home/andreas/glibc/glibc/manual'
make[1]: *** [manual/subdir_install] Error 2
make[1]: Leaving directory `/home/andreas/glibc/glibc'
make: *** [install] Error 2

Fixed for me with:

diff --git a/manual/maint.texi b/manual/maint.texi
