the "-s" flag derives from LD(1):

     -s   Strip the symbolic information from the output object file.

this will pare-down the size of yer final executable by a [potentially]
significant amount.  the "-s" flag seems to me to be primarily useful 
when yer generating yer final finished-version of the executable file
yer making.  at this point, since all symbolic info is now gone, there
h'ain't much use re: any kind of debugging since any such minimal hooks
still in the executable are now gone.  (like if you generate a 

"Segmentation fault (core dumped)"

and then try to do a 

dbx executable-name
(dbx) where

you won't be able to get the standard kind of line number/statement-it-
failed-on feedback but instead will only see things like:

warning: Has no symbol table -- very little is supported without it
)
