[PATCH 3.16 121/233] tags: honor COMPILED_SOURCE with apart output directory

[Ben Hutchings]

3.16.48-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Robert Jarzmik <robert.jarzmik@xxxxxxx>

commit cbf52a3e6a8a92beec6e0c70abf4111cd8f8faf7 upstream.

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")
