| 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. |
