Why do I extensively use that option, though I'm not a packager:

everything (cf. above)
* Having no symbols / debug-info is rather unhelpful for both
debugging, and profiling though perhaps it's a reasonable
default for size reasons

Thank you both for this justfication,
which i've shamelsellsy stolen for the commit message ;-)

so if you want to do profiling you simply have to look up which one your
particular architecture uses first to get meaningful numbers.
No you shouldn't! That what the build systems are for:
