[RFC PATCH v4 03/37] tools: bug: Remove duplicate definition

From: Chen Zhongjin
Date: Fri Apr 29 2022 - 05:47:26 EST


From: Julien Thierry <jthierry@xxxxxxxxxx>

Under tools, bug.h only defines BUILD_BUG_ON_ZERO() which is already
defined in build_bug.h. This prevents a file to include both headers at
the same time.

Have bug.h include build_bug.h instead.
