build-linux.sh error and workaround

[ecv80]

Describe the bug
./build-linux.sh --clean throws:
./build-linux.sh: unrecognized option '--clean'
./build-linux.sh: missing operand
Try './build-linux.sh --help' for more information.

To Reproduce
Steps to reproduce the behavior:

1. Follow Linux install instructions up to and including this step "Run ./build-linux.sh --clean"

Expected behavior
Shouldn't throw errors and just clean.

Screenshots
n/a

Desktop (please complete the following information):

• OS: Ubuntu 18.04.1 LTS
• Host n/a
• Version git master

Additional context
Another user and I got the aforementioned error when trying to build.
It's something to do with argument parsing.
I don't know how getopt works, so I worked around it using sed.
I also switched the help and verbose options since they seem to be inverted.
I was able to build but can not test it to confirm it all works as I have no vst3 host. LV2 appears to be the generally desirable option as per some discussions and popular hosts roadmaps.
Here's the modified script: https://pastebin.com/AhmwMAa6

@jsakkine changed it to not use --. We need to update docs.
Run ./build-linux.sh clean.
which doc did you read?
Thanks!

-- has been removed from README.md

Hi @ecv80 we updated the README this morning to include the latest directions on how to build. Sorry about that! You caught the package in the 12 hours between us changing the arguments and updating the docs!

If you look at the README now they work with the code at master.

I'm going to close this issue. Please reopen it if you still experience problems.

Thank you.
