In addition to use ${srcdir} and deliver ${NOTMUCH_SRCDIR} where needed,
source from ruby bindings had to be copied to the out-of-tree target
directory -- if the source files in source directory were referenced
in build and there were also built object files there, those could have
been considered as target files (and then not found when attempting
to create bindings/ruby/notmuch.so).
The usual make message on everything being up to date is:
make: Nothing to be done for 'all'.
However, since

build: integrate building ruby bindings into notmuch build process
if one doesn't have the ruby dependencies installed, the message has
been:
Missing dependency, skipping ruby bindings
Restore the usual behaviour by dropping the message. It's redundant
during build anyway, since the configure script already outputs:
Checking for ruby development files... No (skipping ruby bindings)
This is supposed to help build on systems like MacOS with different
conventions for naming shared libraries. We have already computed the
relevant names, so doing it again in ruby seems like a bad idea.
Because ruby generates a Makefile, we have to use recursive make.
Because mkmf.rb hardcodes the name Makefile, put our Makefile{.local}
in the parent directory.
