[Buildroot] Error with libusb-0.1.12

[softa at ttechgroup.com]

This is very old problem ... libusb contains 2 libraries, one in pure C, and 
other in CPP .... if you enable the CPP compiler in toolchain everyting will 
be ok, but in the other case you must modify libusb makefiles ....

for example: at least add CXX=""

...
$(LIBUSB_DIR)/.configured: $(LIBUSB_DIR)/.unpacked
        (cd $(LIBUSB_DIR); rm -rf config.cache; \
                $(AUTORECONF) && \
                $(TARGET_CONFIGURE_OPTS) \
                $(TARGET_CONFIGURE_ARGS) \
                ac_cv_header_regex_h=no \
                CXX="" \
                ./configure \
                --target=$(GNU_TARGET_NAME) \
                --host=$(GNU_TARGET_NAME) \
                --build=$(GNU_HOST_NAME) \
                --prefix=/usr \
                --disable-debug \
                --disable-build-docs \
        );
        touch $(LIBUSB_DIR)/.configured
...
