Subject: Makefile: fix dependencies for generated .h, .c
X-Git-Tag: TizenStudio_2.0_p2.3~1942^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a2c54b0578da18add46c2e93521fa2bcb7380ebe;p=sdk%2Femulator%2Fqemu.git

Makefile: fix dependencies for generated .h, .c

We have a single rule generating .c and .h files,
so .h doesn't depend on .c: both depend on the
source schema.

Fix Makefile to reflect that - without this,
if .c is there and .h is missing, Makefile does
not know how to remake .h and assumes it's
a dummy target, triggering endless rebuilds.
