[Bug ld/12001] New: Linker includes archive members when symbols therein have already been defined

[mark at codesourcery dot com]

In this scenario:

f.c
===
void f() {}

main.c
======
int main () { f(); }

$ gcc -c f.c
$ ar cr libf.a f.o
$ gcc main.c -Wl,--defsym=f=4 -L. -lf

the linker pulls in f.o from libf.a, even though f has been explicitly defined
on the command line.

As described here:

http://sourceware.org/ml/binutils/2010-09/msg00110.html

the consensus is that this is a defect in GNU LD and in Gold.
