You can link all your object files into one:

$ ld -r -o all.o foo.o bar.o baz.o

then strip unwanted symbols with {objcopy,strip} -N (or better yet,
use {objcopy,strip} -K to strip all symbols except the ones you want
to export)

this is precisely what we do with klds to reduce namespace pollution.
