This patch is not needed as static build has been disabled since
commit ad8c327053

Moreover, pthread dependency should be correctly retrieved from
libusb-1.0.pc

-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.
