treewide: add ORIG_PATH variable
Add a variable that stores the original value of $PATH
in the host system's shell, before Make alters it.

This can be useful for when it is necessary
to ignore symlinks and programs made by the build system.

Define this new variable before all instances of
'export PATH:=' or similar.
