Merge "Build output directory should be an absolute path."

# The following environment variables affect the result:

#   TARGET_PRODUCT        target device name, e.g., 'aosp_blueline'

#   TARGET_BUILD_VARIANT  variant, e.g., `userdebug`

#   OUT_DIR               where the build is happening (./out if not specified)

#   OUT_DIR               absolute path  where the build is happening ($PWD/out if not specified})

#   DIST_DIR              where the resulting all.kzip will be placed

#   XREF_CORPUS           source code repository URI, e.g., 'android.googlesource.com/platform/superproject'

#   BUILD_NUMBER          build number, used to generate unique ID (will use UUID if not set)

# If OUT_DIR is not set, the build will use out/ as output directory, which is

# a relative path. Make it absolute, otherwise the indexer will not know that it

# contains only generated files.
