[PATCH v2] Makefile: Fake external blob with BINMAN_ALLOW_MISSING=1

[Simon Glass]

This flag was lost by a previous change and has never been restored.
Without it, binman cannot fully handle missing blobs which are
themselves inputs to mkimage.

Discussion on this at [1] indicated that this was necessary but the
patch was not updated.

Restore the flag so that all missing blobs are reported.
