I'm unsure.
My understanding is that if the wscript file uses
<var>.load('gnu_dirs') then waf evaluates the --libdir <dir> parameter
given.

If that is true then one should not move the directory configuration
to the waf class, as each project may or may not have the
load('gnu_dirs')

https://github.com/Freescale/libimxvpuapi/blob/master/wscript#L61

It looks that samba also uses waf and the waf-samba.bbclass is
actually doing what you propose:
http://cgit.openembedded.org/meta-openembedded/tree/meta-networking/classes/waf-samba.bbclass

I'll check some more and report back.
