Commit v1.11.2-114-g693557c of 2012-01-16 (Merge branch 'maint'
into branch-1.11) 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.
