[Xen-devel] [PATCH 15/46] tools/libxl: use buildmakevars2header to create _paths.h

[Olaf Hering <olaf@xxxxxxxxx>]

Replace usage of buildmakevars2file with buildmakevars2header. The macro
generates a C header file, so remove code which converts shell variables
into C defines. Also update the dependency, the macro itself creates a
dependency for _paths.h. A temporary file is not needed anymore.
