Subject: Do not install m4 files

Do not use --install when calling aclocal.  That flag instructs aclocal to
copy third-party files to the first -I directory.  The intention here is to
copy files to the package build dir (m4).  However, our toolchain prepends
the build-system's m4 dir to the list, causing the --install flag to
install an older version to the buildsystem m4 dir, causing failures in
other packages.
