This is a misinterpretation of my data. The effective space requirement
is raised by factor 10 with debugging information.

For the build it is marginal. Until the size themself produces cpu
usage, e.g. with ccache, which at least I use often to shorten the build
time. On runtime it also seems negligible, at least on powerpc, s390 and
x86, it adds a hook into the fault handler for kernel addresses.
