This macro is not provided by autoconf.  (It's a shame that the macro
author abused the AC_ namespace instead of putting it in another
namespace, because it means if autoconf ever DOES implement this macro,
it will break this third-party code.)  You'll need to track down the
implementation of AC_LIB_HAVE_LINKFLAGS before I can offer further

$(LIBUSB-1.0) is not a valid make variable name.  You probably want:

a_LDADD = $(LIBUSB_1_0)

(autoconf and automake both tend to normalize - and . into _).  But
whether that will help or not goes back to what AC_LIB_HAVE_LINKFLAGS is
doing under the hood.
