Unused RTS symbols disappearing in some flavors?

[Ömer Sinan Ağacan]

Hi,

When I build RTS with flavors other than quick (and maybe others) unused symbols
get removed, which makes debugging harder. Does anyone know what setting to add
to build.mk to make sure symbols won't be removed? Ideally I should be able to
add one line at the end of build.mk and the symbols should not be removed
regardless of the flavor.

Thanks,

Ömer
