In general this can not work.  You can only apply the bitwise-or
operator to absolute values.  A label is not an absolute value; it
will not become an absolute value until the linker assigns it a
value.

The wrong section error occurs because LABEL is not in the absolute
section.  We might be able to give a better error message here; it's
an odd case that probably rarely arises.
