Subject: [PATCH v4 03/12] selftests/nolibc: fix up O= option support
To avoid pollute the source code tree and avoid mrproper for every
architecture switch, the O= argument must be supported.
Both IMAGE and .config are from the building directory, let's use
objtree instead of srctree for them.
If no O= option specified, means building kernel in source code tree,
objtree should be srctree in such case.
