Makefile: Rework NI-845x detection

Since the NI-845x is a Windows only proprietary library, disable it by
default. Use `HAS_LIB_NI845X=yes` to enable it. The default search path
is `${PROGRAMFILES}\National Instruments\NI-845x\MS Visual C` and can be
overwritten by `CONFIG_NI845X_LIBRARY_PATH`. Use
`CONFIG_LIB_NI845X_CFLAGS` and `CONFIG_LIB_NI845X_LDFLAGS` for setting
the cflags and ld flags manually.
