Comment:
According to <https://github.com/llvm/llvm-project/issues/44186>, symlinking `gfx909` to same file `gfx900` will work. However, Void will not accept it until upstream accept the fix.

Eigen is header only library. In this case, instead of creating empty base package and putting everything into `-devel`, only base package exists. Simply put `eigen` into makedepends.
