Actually, the increase is < 100KB on i386 (not 780KB).
("du -c /sbin/mount*" reports "103" for the old way, versus "201"
after this change).

Also, if you're that concerned about disk space for such small systems,
use crunchgen; it's even more space efficient than shared libraries.

This change seems fairly non-intrusive, makes the build of mount a bit
simpler, and probably makes it much easier to remove support for file
systems you don't need (rather than compiling support for every file
system into /sbin/mount).  IIRC, Jaromir did the hacks to merge this
a couple of years ago to save 1.7MB of space in /sbin when we didn't
have a dynamically linked /sbin.
