Not that I know of.

I usually create a little compile script which sets the environment variables the way I want, and calls make or gmake appropriately.

For the test suite you can set (if necessary):
  test_cmp
  TAR

'git grep' sometimes calls native grep. You can disallow this by setting the Makefile variable NO_EXTERNAL_GREP.

And of course SHELL_PATH can be used to set the path to the shell that all shell code should be executed with.
