Weak linkage doesn't work as expected

I am using the weak linkage feature of the Real-View Development suite. It appears that a function that is declared as weak is replaced with a NOP regardless of whether the function actually exists in the image. My original understanding of this feature was that the weakly declared function would not be replaced with a NOP unless it was unresolved at the link stage.
Is there a linker option available to tell the linker to use a weakly defined function which has been compiled and should actually exist in the image?
Thanks in advance.

If you can put all the weakly referenced functions in sections called "keepme" then you could use --keep="*(keepme)". Or you could just use --no_remove if that didn't keep too many things that you did want removed.
