Make Config.mk's definition of buildmakevars2file and tools/libxl/Makefile's rule for _libxl_paths.h generate their files to temporary files and only rename them into place if the intended file has changed. This gets rid of unnecessarily compilation and link steps. Add *.tmp to .hgignore. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com> Acked-by: Keir Fraser <keir.fraser@citrix.com>
