builtin libs in waf are a bit funny, and part of the issue would come
form the interaction between waf's dependency reducer and version
scripts that eliminate public symbols.  You won't see the -lreplace for
a builtin lib - builtin libs become subsystems, ie added to the object
list.  What I think has happened here is that it has become a subsystem
of some other library, which isn't then exporting the replace symbols.

I suggest you follow Jelmer's example for debian, and instead depend on
libbsd, to avoid packaging libreplace.  (ccan may be more trouble, and
for that I want to re-enable the private library extension for bundled
libs, but only for libraries that we know contain no static data).
