ignore cvslatest errors in expert mode
Handle git and mercurial for reproducible builds.
for mercurial, use the latest revision instead of limiting the output to 1
(requested by joerg)
handle different flavors of date(1)
kre@ does not like the subshell :-)
Add a new operation "mkrepro-timestamp" to extract the timestamp a
build with -P would use. Example usage:
        ./build.sh -T /usr/tools -P mkrepro-timestamp
This allows us to extract this information once, make other use of it,
and replicate it on other machines with -V MKREPRO=yes -V MKREPRO_TIMESTAMP=..
