Commit 2b02882ebbbc "libxl: add infrastructure to track and query 'recent' domids" added a call to clock_gettime() into libxl. The man- page for this states: "Link with -lrt (only for glibc versions before 2.17)." Unfortunately Centos 6 does have an glibc prior to that version, and the libxl Makefile was not updated to add '-lrt' so the build will fail in that environment. This patch simply adds '-lrt' to LIBXL_LIBS unconditionally, as it does no harm in newer environments.
