OK, it's true you can see it as: one allows to override the LDFLAGS,
the other drops a bogus hardcoded path.

-I$(STAGING_DIR)/usr/include is definitely useless as it's the default
search path for headers for the Buildroot cross-compiler, but that's
not what you were adding: you were adding
-I$(STAGING_DIR)/usr/include/X11R6, which is not in the default search
path for headers.
