Delete two m4files ax_code_coverage.m4 and ax_check_enable_debug.m4
to avoid installing conflicts. These two files can be installed by
gnome-common from oe-core, even if the files in gnmoe-common is
copied from autoconf-archive(the reason is that the old version
autoconf-archive don't provide the two files).
After upgrading to the new version, we need to drop them in meta-oe
and then set rdepends to gnome-common(oe-core)
