[PATCH 1/1] build: delete the default .SUFFIXES

[Tomi Ollila]

All implicit rules in notmuch Makefiles are "pattern rules"; Deleting the
default suffixes (to support obsolete, old-fashioned "suffix rules") from
make reduces the output of 'make -d' by 40 to 90 percent, helping e.g.
debugging make problems.
