It seems that on sn-devel we have already a system talloc that's why we 
might only need to specify --bunled-libraries=!tdb

Can you develop this point ? what prevents samba to use the internal 
library once we fix the waf code for the detection of ctdb.h ?
Because here ihmo the problem is that when we are building with the 
bundled library we don't add the search path for the bundled lib into 
waf's snippet.
