[PATCH 3/4] rxvt: improve aclocal.m4 handling

[Ross Burton <ross.burton@arm.com>]

I don't know why we copy aclocal.m4 to acinclude.m4 to avoid
autotools.bbclass deleting the upstream hand-maintained aclocal.m4, but
we do.

A neater fix is to exclude aclocal, which has the side-effect of not
deleting aclocal.m4 in do_configure.
