In this log, I see:

configure:23922: checking for working iconv
configure:24066: gcc -o conftest -O2 -Wall -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=3 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection -Werror=return-type -flto=auto -g  -flto=auto conftest.c  >&5
configure:24066: $? = 0
configure:24066: ./conftest
configure:24066: $? = 16
configure: program exited with status 16

and status 16 means that there is no EUC-JP converter.

This is now the second distro I hear of, that ships glibc without any loadable
iconv converters by default.

I have therefore reported
https://sourceware.org/bugzilla/show_bug.cgi?id=32437
in the hope that glibc makes it easier to distros to ship a reasonable set
of iconv converters.
