    Accept GUILE 2 without extra configure options

    A run of the regression tests at "5f4cf7bd38 - Parse inline scheme
    using per-_expression_ port" shows the following issues compared to
    GUILE 1.8

    * changed interleaving of error and progress messages.

    * floating point rounding differences.

    * an encoding error in song-basic-nonenglish.ly

    As of a19aed1 "GUILE2: Scale GC heap with the number of smobs",
    performance for large scores with GUILE 2.2 is just ~25% slower on
    large scores.

    The regression test (make test-baseline) is 67% slower. This can
    partly be explained because of the slower startup: until we can
    support pre-compiled files, we incur a 1.5 sec extra delay for parsing
    .scm files.

GUILE 1.8

• changed interleaving of error and progress messages.

• floating point rounding differences.

• an encoding error in song-basic-nonenglish.ly

As of a19aed1 "GUILE2: Scale GC heap with the number of smobs",
performance for large scores with GUILE 2.2 is similar to GUILE 1.8.

For small scores, a 1.5 sec extra delay (due to byte-code compilation
of .scm files) remains, but this does not warrant the "highly
experimental" monniker.
