Nope:
echo "void sub1() { printf("sub1\\n"); }" >sub1.c
echo "void sub2() { printf("sub2\\n"); }" >sub2.c
cc -c sub1.c sub2.c
ar crv arch.a sub1.o sub2.o
echo "main() { sub1(); exit(0); }" >tst.c
cc -o tst tst.c arch.a
nm tst | grep sub
shows only sub1, at least on Solaris.

I noticed there were similar flags for -I header files in a recent snapshot
but don't know what to do for libraries. Ah, the ld man page says -Z will
tell it not to search the standard libraries. I have to go, will try it
tomorrow.
