+ * configure.in (AC_PROG_RANLIB): No longer required as we now use
+ AC_CHECK_TOOL in AC_LIBTOOL_SETUP.
+ * libtool.m4 (AC_PROG_LIBTOOL): Pass the $build variable to
+ ltconfig.
+ (AC_PROG_RANLIB): replaced with AC_CHECK_TOOL.
+ * ltconfig.in (build): new variable to hold the build triplet
+ which is now checked for unless --no-verify is specified.
+ (--build): new argument to set the build triplet.
+ (ranlib): Prefer ${host_alias}-ranlib[.exe] if $build is different
+ to $host.
+ * doc/libtool.texi (Invoking ltconfig): Document --build option.
+ * NEWS: Note --build option.

and accepts the following options:
@table @samp
+@item --build=@var{build}
+Set the build system to be different to the host system. This creates a
+libtool which prefers build tools which are prefixed by the host alias over
+the standard tools. For example, specifying @code{--build=i486-pc-linux-gnu}
+on a host described by i486-pc-cygwin would create a libtool which used
+@code{i486-pc-cygwin-ranlib} in preference to @code{ranlib} if present. This
+is useful for cross build environments.
+
@item --debug
Dump a trace of shell script execution to standard output. This
produces a lot of output, so you may wish to pipe it to @code{less} (or
