Po Lu c6a052f2fe Respect --disable-build-details in Android builds
* java/Makefile.in (BUILD_DETAILS, GEN_BUILD_DETAILS): New
variables.
(install_tmp): Tolerate failures in generation of metadata files
and prefix commands for such generation with GEN_BUILD_DETAILS.

* lisp/version.el (android-read-build-system)
(android-read-build-time): Return nil if metadata file does not
exist.
