[PATCH AUTOSEL for 3.18 072/102] tags: honor COMPILED_SOURCE with apart output directory

[Sasha Levin]

From: Robert Jarzmik <robert.jarzmik@xxxxxxx>

[ Upstream commit cbf52a3e6a8a92beec6e0c70abf4111cd8f8faf7 ]

When the kernel is compiled with an "O=" argument, the object files are
not in the source tree, but in the build tree.

This patch fixes O= build by looking for object files in the build tree.

Fixes: 923e02ecf3f8 ("scripts/tags.sh: Support compiled source")
