My knowledge about the interal workings and building procedures is so close
to nil that I don't even understand the relation of your answer to my
question. I'm really sorry since I expect that this is entirely my fault!

Anyway, I now succeded in compiling 2.19.15  by downgrading to GCC 5.5.0
(GCC 4.8.5 didn't pass autogen.sh, and GCC 6.5.0 aborted during compilation
just like my "usual" GCC 7.4.0).

The misplaced-note-head bug (as exposed in the MWE in
https://sourceforge.net/p/testlilyissues/issues/5303/) first appears with:

    Issue 216: ability to change staff line spacing inside a \layout{} block

    This uses the staff-space setting from the \layout block (if set) for
    determining staff spacing.

    It apparently does not help with horizontal spacing, though.
