Disabling building of introspection data will not guarantee absence of
build failures, I'm afraid. Some recipes will work just fine unchanged,
but others, including gstreamer, do need custom fixing, usually because
they have non-standard locations for m4 macros, or those macros themselves
are non-standard. So you need to rebase your recipes on top of those
available now in oe-core, and particularly this snippet will fix the
immediate problem you have above:

delete_pkg_m4_file() {
        # This m4 file is out of date and is missing
PKG_CONFIG_SYSROOT_PATH tweaks which we need for introspection
        rm "${S}/common/m4/pkg.m4" || true
}

do_configure[prefuncs] += " delete_pkg_m4_file"
