Thanks, they look (almost) good! Could you submit them, one mail per
patch, preferably using git send-email?

On libassuan, please wrap the help text, and add a final newline at the
end of the .mk file.

On libgpgme, please wrap the help text, add the final newline at the
end of the .mk file. The --with-gpg=/usr/bin/gpg doesn't look very
good. gpg is not a mandatory dependency of Buildroot, so if libgpgme
really needs gpg, then we should build host-gnupg I guess. But does it
really need it? Can you detail this --with-gpg option? Or maybe it's
just the path where gpg will be installed on the target? If it's the
case, then maybe a comment would be appropriate to clarify this.

In the opkg patch, in the .mk file, you should use
BR2_PACKAGE_OPKG_GPG_SIGN in your condition rather than
BR2_PACKAGE_LIBGPGME. Also, in your Config.in, you add GNUPG as a
dependency, but it is not listed in the .mk file. This is sometimes
correct if it is only a runtime dependency, in which case we usually
put a comment in the Config.in just above the corresponding select line.
