After commit b3f1c8c413bc83e4a2cc7a63e4eddf9fe6449052 "qemu-pr-helper: use new libmultipath API", QEMU started using new libmultipath API, which is not available on CentOS 7.x. This fixes that by probing the new libmultipath API in configure. If it fails, then try probing the old API. If it fails, then consider libmultipath not available. With this, configure script defines CONFIG_MPATH_NEW_API that is used in scsi/qemu-pr-helper.c to use the new libmultipath API.
