libxl, buildmakevars2file: Do not relink libxl each time
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.
