+configure.ac: explicitly add pthread cflags/libs in the libusb test
+
+If libusb-config does not exist, LIBUSB_CFLAGS and PTHREAD_CFLAGS will be
+empty, and the test for libusb will be performed without additional flags.
+However, when libusb needs threads, some extra flags are needed (depending
+on the platform), like -pthreads, -lpthread, etc. Without these flags, the
+test for libusb_init() will fail to link correctly, and pcsc-lite will fail
+detecting libusb.
