    build: Use m4 directory for macros
    
    Previously, ACLOCAL_AMFLAGS was set to ${ACLOCAL_FLAGS}. This caused
    problems when running libtoolize --force --copy as part of autoreconf.
    On JHBuild when ACLOCAL_FLAGS was set to the build tree's share/aclocal
    directory, libtoolize would actually remove the libtool macros from
    there.
