Binutils "strip -N <symbol> foo.o" strips only <symbol> from the output.
Elftoolchain strip strips everything.

% cat foo.c
int
add1(int a)
{
        return a + 1;
}

int
add2(int a)
{
        return a + 2;
}

% cc -g -o foo.o -c foo.c

% strip -N add1 -o foo.bu.o foo.o
% file foo.bu.o
foo.bu.o: ELF 64-bit LSB relocatable, x86-64, version 1 (FreeBSD), not stripped
% nm foo.bu.o                  
0000000000000020 T add2

% elftcstrip -N add1 -o foo.elftc.o foo.o
% file foo.elftc.o
