Yes, in op's case, but not in yours, AFAIRC.
// anyway, I patch your makefile for:
```
34 › › -e 's@^(prefix).*@\1=/usr@' \
35 › › -e 's@(.*LUA_DIR.*/lua/.*shell )lua( -e "print.*)@\1${LUA_IMPL}\2@'
```
(i.e. to call proper lua$ver instead lua) ;)

Nope. It is not "defining environment variables". It is passing arguments to
`make` (which are force values over environment variables and vaues from
makefile itself).
While "?=", and, AFAIRC, ":=" too — allows to use exactly environment
variables.
