autotools.eclass: use --system-acdir for aclocal
We need to instruct aclocal that it might find macros in both
${BROOT} _and_ ${SYSROOT}.
- A classic example within BROOT is autoconf-archive.
- A classic example within SYSROOT is, say, libogg. A fair amount of
codec software installs its own macro to help locating it (but this
is in no ways limited to that genre/area).
The correct position for a dependency like libogg is DEPEND, and yet
the status quo doesn't mean that aclocal is obligated to check in ${ESYSROOT}
which is where DEPEND-class dependencies are guaranteed to be installed.
We can't rely on these being in BDEPEND -- in fact, most of the time,
they won't be. If we wanted to rely on macros always being provided by
BDEPEND, we'd have to duplicate a considerable number of dependencies
in both BDEPEND + DEPEND, with the unnecessary cross-compilation that would
entail too: it makes far more sense to just tell aclocal to look in the
right place (an extra location).
