Even without -g, using "ls -l" doesn't give a very exact figure, as it
includes symbol tables and other metadata, but doesn't count BSS
(which is very relevant for the memory footprint).  Using "size" gives a
better indication of how much it will add to a static binary.

Dreamcast build, ls -l:

-rwxrwxr-x   1 marcus   marcus   2312150 Jul 14 14:00 scumm.plg
-rwxrwxr-x   1 marcus   marcus   1476130 Jul 14 14:00 kyra.plg
-rwxrwxr-x   1 marcus   marcus    768356 Jul 14 14:00 gob.plg
-rwxrwxr-x   1 marcus   marcus    717755 Jul 14 14:00 agos.plg
-rwxrwxr-x   1 marcus   marcus    545700 Jul 14 14:00 saga.plg

size:

scumm.plg: 0 + 1708348 + 3052 = 1711400
kyra.plg: 0 + 1096324 + 64701 = 1161025
parallaction.plg: 0 + 323224 + 258060 = 581284
gob.plg: 0 + 580344 + 8 = 580352
cruise.plg: 0 + 162844 + 379380 = 542224

The top two are the same, but parallaction comes up third because of
1/4 megabyte of BSS.  (Ok, I used a dynamic build here, but the
results should be about the same with static libraries.)
