When trying to generate standalone toolchain, getting this error:

$ crew.dir/crew make-standalone-toolchain --arch=arm64 --api-level=26  --install-dir=/tmp/toolchain-arm64-api26
Warning: using system ruby

1. Currently, there is no support for api levels > 24.
2. I could not reproduce an error:
   zuav@ithilien$ ./crew -b make-standalone-toolchain --arch=arm64 --api-level=24 --install-dir=/tmp/toolchain-arm64-api24

3. Could you please rerun your command with -b option, like this:
