[adding the list back to CC]

What version of libtool is generating this? Where is the -r coming from?
Why are you passing -Map instead of -map?

Passing -Wl,-map,libbuffer.map will likely work, but I am not sure why
the -Wl, quoting was removed above. Nor am I sure why gcc generates no
warning or error when it sees -Map, and just ignores it.
