The bug reproduces only in a prefixed environment. And if you have a prefixed
binutils install, the steps mentioned by me should reproduce the problem:

1. run the script
2. cd /tmp/mydir
3 gcc -shared -o libcwait.so mysymbol.o
4 mv libcwait.so $PREFIX/usr/lib/libcwait.so
5. gcc -o mymain mymain.o -L$PREFIX/usr/lib -L/usr/lib -lcwait

You can use any other name for library. It should be already present in 

The link will fail with undefined symbol.

This is the minimal I can do. The bug is pretty obvious in prefix env.
