[Buildroot] [PATCH 1/1] package/sispmctl: fix static linking

The static linking doesn't works with libusb-compat when using libusb-config.
Also the CFLAGS initialization with libusb-config --cflags is comented out.

Based on libftdi's patch, add the support for pkg-config to link sispmctl
correctly.

This allow to add correct include directory to CFLAGS
(Add -I$(STAGING_DIR)/usr/include and -I$(STAGING_DIR)/usr/include/libusb-1.0)
Also add needed libraries during static linking (-lusb -lusb-1.0 and -pthread)

Since configure.ac is modified, the configure script needs to be regenerated
with autoreconf.
