We're seeing sporadic errors like

  ENVC    include/generated/env.txt
  HOSTCC  scripts/basic/fixdep
  ENVP    include/generated/env.in
  ENVT    include/generated/environment.h
  HOSTCC  tools/printinitialenv
/bin/sh: 1: scripts/basic/fixdep: not found
make[1]: *** [scripts/Makefile.host:95: tools/printinitialenv] Error 127
make[1]: *** Deleting file 'tools/printinitialenv'
make: *** [Makefile:2446: u-boot-initial-env] Error 2
make: *** Waiting for unfinished jobs....

where sometimes the "fixdep: not found" is instead "fixdep: Permission
denied" and the Error 127 becomes 126.

This smells like a race condition, and indeed it is: Currently,
u-boot-initial-env is a prerequisite of the envtools target, which
also lists scripts_basic as a prerequisite:

envtools: u-boot-initial-env scripts_basic $(version_h) $(timestamp_h) tools/version.h
	$(Q)$(MAKE) $(build)=tools/env

However, the u-boot-initial-env rule involves building the
printinitialenv helper, which in turn is built using an if_changed_dep
rule. That means we must ensure scripts/basic/fixdep is built and
ready before trying to build printinitialenv, i.e. the
u-boot-initial-env rule itself must depend on the phony scripts_basic
target.

It is entirely possible at this point to have platforms in U-Boot that
do not have board-specific C code (just Kconfig or environment) and so
make it optional to have to descend in to and then build in the board
directory.

If the source .env file changes to one that is also older than the
generated env.txt file then the .env file is not regenerated. This
means when switching board configs we do not regenerate the env.

This can be tested with:

$ make j721e_evm_a72_defconfig
$ make # this may fail to complete but that is okay for this test
$ make am64x_evm_a53_defconfig
$ make
$ vim include/generated/env.txt

Note this is still the J721e env not the AM64 config as expected.

As ENV_FILE is set based on configuration, regenerate anytime
autoconf.h changes.
