xen.git commit babeca32 added a pkgconfig file for libxenlight, allowing libxl apps to determine the location of Xen binaries such as firmware blobs, device emulator, etc. This patch adds support for xenlight.pc in the libxl driver, falling back to the previous configure logic if not found. It introduces LIBXL_FIRMWARE_DIR and LIBXL_EXECBIN_DIR to define the firmware and libexec_bin locations. If xenlight.pc does not exist, the defines are set to the current hardcoded paths. The capabilities' <emulator> and <loader> elements are updated to use the paths. Signed-off-by: Jim Fehlig <jfehlig@suse.com>
