-static-pie was not an option for musl, but -static and -pie were. Is this just on my system (4.15.0-122-generic #124-Ubuntu SMP Thu Oct 15 13:03:05 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux)

@frumioj Based on your kernel version I'm guessing you're running Ubuntu Bionic or Xenial (with an edge kernel). I'm guessing the gcc version in both of those releases are too old to have the compiler options listed here in the documentation.

Could you share the output of gcc --version?

edit: For reference, my compiler is gcc (GCC) 10.2.1 20201005 (Red Hat 10.2.1-5)

I added gcc-8 to my machine, and recompiled with that. It is now working. I will close this PR. Thanks!

[frumioj]

Since Ubuntu 18.04 (at least) comes with gcc 7.4, and it seems the minimum required version is gcc 8.4 (that's what I get for sudo apt install gcc-8) I would recommend adding a note to the README file.

[frumioj]

Actually scratch that. It looks like you need a minimum of gcc-9 with the backported mtune=znver2 switch for musl-gcc. I still recommend a note on the README :)

That reminds me, that mtune=znver2 can be removed, if it doesn't work for all.
