Comment (by lbschenkel):

 I agree that it is not very straightforward. This reflects NeoMutt build
 options (there's no `hcache` there either and it is controlled by enabling
 a storage back-end). I reworded the variant descriptions to make that
 clearer:
 {{{
    db4: Enable header cache using Berkeley DB database
    db5: Enable header cache using Berkeley DB database
    gdbm: Enable header cache using GNU dbm database
    kyotocabinet: Enable header cache using Kyoto Cabinet database
    lmdb: Enable header cache using LMDB database
    qdbm: Enable header cache using QDBM database
    tokyocabinet: Enable header cache using Tokyo Cabinet database
 }}}
