  Log Message:
  -----------
  Disable rosegment for old Android versions.

The unwinder used by the crash handler on versions of Android prior to
API 29 did not correctly handle binaries built with rosegment, which is
enabled by default for LLD. Android only supports LLD, so it's not an
issue that this flag is not accepted by other linkers.
