This is an unfortunate artifact of autoconf --help handling with
recursive configure scripts. You'll see both mentioned in the output
of gcc/configure --help. --with-build-sysroot needs to be handled at
the top level in order to pass down the --sysroot option when
compiling libraries; therefore, it appears in the top level --help
output. --with-sysroot does not need to be handled at the top level;
therefore, it does not appear in the top level --help output.
