trylink: explain how to modify link and drastically decrease amount
of padding (unfortunately, needs hand editing ATM).
*: add ALIGN1 / ALIGN2 to global strings and arrays of bytes and shorts
size saving: 0.5k

*: s/include "busybox.h"/include "libbb.h"

It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

implemented. (Plus a bit more of bbsh leaking in from my tree, but it
shouldn't hurt anything and I'm lazy...)
