Subject: android: don't unconditionally use execinfo.h
X-Git-Tag: 071012131707~48
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=007204544c4fd8c75b6c61d240f203a9cabc7591;p=profile%2Fivi%2Fqtdeclarative.git

android: don't unconditionally use execinfo.h

android (a superset or subset, depending on your POV) of Linux doesn't seem to
have execinfo.h, so disable it there.

also simplify the conditional a little so we don't have to alter this all over
the place if the platform support changes in the future.
