Jörg Thalheim 8f6c09cfb9 [Runtime/pal_loader] Do not depend on absolute path for tools
On NixOS/Guix tools are not installed under /usr/bin but are composed
as symlink trees from immutable packages under /nix/store.

Since pal_loader script already relies on bash to be in the PATH env
var, we already have PATH defined here and can use relative paths.
