[maint] tests: put AM_PROG_CC_C_O before AC_OUTPUT to help losing compilers

[Peter Rosin]

When AM_PROG_CC_C_O is after AC_OUTPUT, the compile script
is not used even if needed, causing testsuite fails if
libtool is not used.

* tests/depcomp8a.test: Uncomment the AM_PROG_CC_C_O macro
in its correct location, as indicated...
(configure.in): ...with this comment.
* tests/depcomp8b.test: Sync with tests/depcomp8a.test.
