Comment 11 for bug 889984

Fix validated on gcc-linaro-arm-linux-gnueabi-2012.01-20120112+bzr2336~win32/ which I picked up from http://people.linaro.org/~michaelh/incoming/binaries/. DS-5 no longer steps in to the function where I observed the problem (__addsf3), which implies that .debug_info is no longer present.
