"-s" is a linker flag so you should use it when linking, not when 
compiling. (Sorry, but I'm a language lawyer.)

MYCFLAGS="-Os -fomit-frame-pointer -fno-keep-static-consts 
-fmerge-all-constants"
MYLDFLAGS="-s -O 3 --sort-common"

I did not try most of these options, so be sure to read the warnings in 
the gcc and ld manuals/info pages.
