Adding a phase here that gets rid of dates and such makes the build
reproducible:

(add-after 'unpack 'pre-configure
           (lambda _
             (substitute* "configure"
               (("PROJECT_build=\"`date`\"") "PROJECT_build=\"\"")
               (("ac_abs_top_builddir=$ac_pwd") "ac_abs_top_builddir=\"\""))))

The synopsis should start with an uppercase letter and not start with
the package name. Perhaps you could erase everything before "API".

The rest LGTM. Could you send an updated patch?
