As I mentioned, I can't use the one that's available as a debian pkg built by Linaro, because I need to use the toolchain in Scratchbox, which has a rather old libc (in its host_shared/lib), and the Linaro one was built against a very new libc.
iirc there was scratchbox rootfs based on Lenny available and this will be newer then Dapper (which is nearly 5 years old now).
I checked with scratchbox.org, and there are no current plans to update the host_shared libc, so, if the CS 4.5.1 doesn't have those same neon optimizations, then my only other recourse is to try and build the linaro 4.5.2 myself (since I need this "yesterday" :P ). So I was hoping the build process that's being used to build the cross for ARM would be documented somewhere, so I could do the same steps, just on an earlier Ubuntu (dapper), but I wasn't able to find anything on the Linaro site.
gcc-4.5 from 'natty' may be buildable even under dapper but you will have to backport some other packages too to make it work. As we do not support anything older then 10.04 'lucid' there will be no work done to make such backport.
