I suspect You are using binutils-2.8.1. I suggest to install 
bnu251b.zip. 

However I haven't verifed Your problem with 2.8.1.

At least I didn't saw local labels in object files both when using 
binutils-2.9.1 (with some patches) and 4th April snaphot of binutils
(with patches practically identical to ones from bnu2951s.zip, only
binaries were built under Linux using cross-compiling)
