[Pkg-samba-maint] Bug#1006863: Bug#1006863: tevent: reproducible-builds: build path embedded in various libraries

[Andrew Bartlett]

I would rather this be discussed and implemented upstream.

For one, the tevent build system is shared with the rest of Samba, and
if possible this should be implemented by default for all 'make
install' runs, just as we do to strip out the bin/default from -rpath.
