    ext/iconv/tests/iconv_mime_encode.phpt: skip for "unknown" iconv

    This test checks the output of iconv_mime_encode() with a target
    charset of ISO-2022-JP. That charset is stateful, though, and there
    are many ways to arrive at a correct answer. Musl has an inefficient
    encoding of it that causes this to fail because the actual output
    differs from (and is much longer than) the expected output. We add a
    SKIPIF for the "unknown" iconv implementation that musl has.
