I confirmed that the release of 1.33 and 1.34 have wrong gpgrt-config.

This is because gpgrt-config was generated file (in terms of automake,
it was the one in bin_SCRIPTS), but changed to the one of
dist_bin_SCRIPTS, during the development of 1.33, and we did not remove
generated gpgrt-config in our build directory.  We should have removed
the generated file in our build directory.

1.35 will fix this problem.
