Subject: [PATCH] Turn on ARM linker --inline

For release and develop profiles, turn on the linker's `--inline`
optimisation. This can save a couple of hundred bytes in a typical
image.

The optimisation replaces branches to small functions with the
inlined code from those functions. And it's possible that the
out-of-line functions can be eliminated.

Setting confined to release and develop builds only, as it can lead to
invalid debug information.
