Subject[PATCH 2/2] scripts/tags.sh: Support compiled source
Date
We usually have interst in compiled files only,
because they are strongly related to individual's work.
Current tags.sh can't select compiled files, so support it.

We can use this functionality like below.
"make cscope O=. SRCARCH=xxxx SUBARCH=compiled"

It must be executed after building the kernel.
