cf: Make local copy of ax_gcc_func_attribute.m4

Make a local copy of ax_gcc_func_attribute from autoconf-archive. This
is needed in order to fix a bug in the detection of the fallthrough
attribute.

Remove ax_gcc_func_attribute.m4 from src/external/autoconf-archive/m4.
Update LICENSE file to point to the local copy in src/cf.
