Do you see a mention of grep and egrep in the configure output?
yes:
checking for grep that handles long lines and -e... /usr/bin/grep
I get nothing like the above, but
checking for egrep... /usr/bin/grep -E
checking for egrep -e... /usr/bin/grep -E
I guess that the support macros for iconv configuration have changed and
thus the EGREP variable is not defined any more. We have to think of a
stable replacement.
It is the fault of autoconf 2.72, actually. Try the patch below.

*** All internal uses of AC_EGREP_CPP and AC_EGREP_HEADER have been removed.
These macros look for text matching a regular expression in the
output of the C preprocessor. Their use has been discouraged for
many years, as they tend to be unreliable; it is better to find a
way to use AC_COMPILE_IFELSE or AC_PREPROC_IFELSE instead. We have
finally taken our own advice.
This change might break configure scripts that expected probes for
‘grep’ and/or the C preprocessor to happen as a side effect of an
unrelated operation. Such scripts can be fixed by adding
AC_PROG_EGREP and/or AC_PROG_CPP in an appropriate place.
The macros affected by this change are AC_C_STRINGIZE,
AC_C_VARARRAYS, AC_FUNC_GETGROUPS, AC_FUNC_GETLOADAVG,
AC_HEADER_TIOCGWINSZ, AC_PROG_GCC_TRADITIONAL, AC_TYPE_GETGROUPS,
AC_TYPE_UID_T, and AC_XENIX_DIR. Many of these macros are themselves
obsolete; if your configure script uses any of them, check whether
it is actually needed.

Subject: [PATCH] Add explicit check for EGREP in configure.ac
It is used in lib/Makefile.am and we were relying some autoconf macros
to define it as a side-effect. This is not the case anymore as of
autoconf 2.72.
