[PATCH] build: require Gettext 1.18.2, for compatibility with future automake

[Stefano Lattarini]

This is necessary to have the gettext-provided m4 files to use
AC_PROG_MKDIR_P rather than AM_PROG_MKDIR_P.  This latter macro,
planned to disappear in Automake 1.14, has already been removed
in the development version of Automake, so that, without this
change, grep fails to bootstrap with bleeding-edge Automake.
