Qt and KDE4 require -mimplicit-it=thumb too. It is disabled in Ubuntu gcc-4.5 and as a result it does not build on armel without setting it in debian/rules (qt4 has it done, kde waits for decision of toolchain maintainers).
The difference is that in Linux, -mimplicit-it is sort of officially required (actually, I believe this toolchain feature got added as a consequence of implementing CONFIG_THUMB2_KERNEL)
In Qt, we require -mimplicit-it by accident - the maintainers do not explicitly support building for Thumb-2. This will be the case for most projects we encounter.
