My testcase was wrong because I was installing into the same
destination directory each time when bisecting (that shortcut normally
works but can cause problems with LLVM changes). When I install into a
fresh directory, it works.
There may (or may not) have been some bug in my original larger case,
but I'll have to re-investigate, and in any case I don't think your
commit was a problem.
