localtime did not set tm->tm_zone properly making pkgsrc emacs core-dump.
Thanks to Masanori Kanaoka.
defflag AWIN_HDMI_DEBUG, AWIN_TCON_DEBUG, AWIN_DEBE_DEBUG, and defparam AWIN_DEBE_VIDEOMEM
Make check_ids take an additional argument (the corresponding source
file) and grep that on error for the missing information, so the user
gets all the info needed how to "FIX MANUALLY".
