Commit v1.11-1750-g9928ea5 of 2012-01-16 (Merge branch 'maint')
reordered the macro calls so that AM_PROG_AR ended up after
AC_PROG_LIBTOOL, which is not allowed. This error went by
undetected since AC_PROG_LIBTOOL was redefined, but that also
removed the ordering requirement making the error benign.
* tests/vala.test: Put AM_PROG_AR before AC_PROG_LIBTOOL.
