By completely omitting --with-jdk-home from autogen.input, I get a
successful build.  configure complains that JAVA_HOME is not set, but
the build continues.

Thank you, Stephan.

Oh my!

  When I first came from OpenOffice to LibreOffice, lo those
  many years ago, I planned to carefully collect all the configuration
  and build problems I encountered, thinking that the compilation
  would be a useful contribution to the project.  I found no problems,
  and that is one of the big improvements in LibreOffice: the build
  system "just works".  A result, though, is that I have needed to
  learn essentially nothing about the build system.
