When a DW_FORM_flag_present attribute comes at the very end of a debug
section, readelf complains about a corrupt attribute because it's
checking to make sure there's at least one byte of data remaining.
This patch suppresses the check when the form is DW_FORM_flag_present.
Committed as trivial and obvious.
