Incremental linking and relocation

My project have a several object files with project internal functions, and one object file which exposes functions for a public interface. My goal is to use incremental linking to combine all object files to a single file, and have this single file only expose the symbols needed for the public interface.

foo.c, public interface.

void bar(void);

void foo(void)
{
    bar();
}

bar.c, project internal function.

void bar(void)
{
}

$ gcc -c foo.c
$ gcc -c bar.c
$ ld -r -o combined.o foo.o bar.o
$ strip -N bar combined.o  
strip: not stripping symbol `bar' because it is named in a relocation

Both functions are already part of the same segment in the same object file, so I believe it should be possible to resolve the relocation during the link step? Is it possible to alter the ld command in order for the relocation not to be needed?
