If you use binary detached signatures (-sb) this is pretty easy. You
can simply concatenate the signature files. We do this for gnupg
releases. gnupg/build-auc/append-signature.sh is a script which helps
with this workflow.
If the messages are armored you need to de-armor (gpg --dearmor) them
first, concatenate and en-armor them. Finnally fix up the armor lines.
