Build error with Alpine >= 3.18.0 and musl >= 1.2.4

[jk779]

An update in Alpine (upgrade to a new musl version) breaks building the gem.

I've attached a PR that workarounds this until gpgme updates. More information in the PR: #181

Now that #181 has been merged, I'm closing this issue.

I just encountered this issue with Alpine Linux too (I had version 2.0.22) after I upgraded to a newer version of Alpine.
I confirm that upgrading gpgme to version 2.0.24 fixed the issue (just in case someone else needs to know how to resolve the issue if they had an older version of gpgme).
