Thanks!

Sorry, forgot do add it right away.  I've applied the patch below, which
also removes the quotes around $AUTOCONF, so it can have arguments.
This is consistent with how we handle $AUTOCONF in the new testsuite.

Cheers,
Ralf

        * tests/tagtrace.test: Allow `$AUTOCONF' to contain arguments.
        Skip if the running `autoconf' version is older than the one
        used to bootstrap Libtool.
