Yeah. I've been doing this for almost 10 years now. It's not APE/cosmopolitan (which also "kinda works" with Nim but has many lowest common denominator platform support issues, e.g. posix_fallocate). However, it does let you have very cross-Linux portable binaries. Maybe beyond Linux.

Some might appreciate a concrete instance of this advice inline here. For `foo.nim`, you can just add a `foo.nim.cfg`:

    @if gcc:
      gcc.exe       = "musl-gcc"
      gcc.linkerexe = "musl-gcc"
      passL         = "-static -s" @end

    if defined gcc:  # nim.cfg runs faster than NimScript
      switch "gcc.exe"      , "musl-gcc"
      switch "gcc.linkerexe", "musl-gcc"
      switch "passL"        , "-static -s"
