Details:

With Autoconf 2.69 and Automake 1.11.6, the use of AX_PROG_JAVAH causes the
following warnings:

    configure.ac:47: warning: AC_ARG_PROGRAM was called before
AC_CANONICAL_TARGET
    ../../lib/autoconf/general.m4:1857: AC_CANONICAL_SYSTEM is expanded
from...
    m4/ax_prog_javah.m4:27: AX_PROG_JAVAH is expanded from...
    configure.ac:47: the top level
    [the aforementioned warnings repeat a number of times]

This seems to happen because of the use of AC_REQUIRE([AC_CANONICAL_SYSTEM])
where AC_REQUIRE([AC_CANONICAL_BUILD]) would suffice. The attached patch fixes
this.
