Revert "scripts/setlocalversion: git: Make -dirty check more robust"
[ Upstream commit 8ef14c2c41d962756d314f1d7dc972b0ea7a180f ]
This reverts commit 6147b1cf19651c7de297e69108b141fb30aa2349.
The reverted patch results in attempted write access to the source
repository, even if that repository is mounted read-only.
Output from "strace git status -uno --porcelain":
getcwd("/tmp/linux-test", 129) = 16
open("/tmp/linux-test/.git/index.lock", O_RDWR|O_CREAT|O_EXCL|O_CLOEXEC, 0666) =
-1 EROFS (Read-only file system)
While git appears to be able to handle this situation, a monitored
build environment (such as the one used for Chrome OS kernel builds)
may detect it and bail out with an access violation error. On top of
that, the attempted write access suggests that git _will_ write to the
file even if a build output directory is specified. Users may have the
reasonable expectation that the source repository remains untouched in
that situation.
