To avoid issues [1] with some projects that call us from a top-level
Makefile that has an 'export' directive or a '.EXPORT_ALL_VARIABLES:'
target, we prevent $(MAKEFILE_LIST) from being exported, thereby
greatly reducing the size of the environment.
[1] Typically, the build succeeds the first time (because there is no
.cmd/.d files yet), then the second invocation of make fails with:
CHK out/arm-plat-vexpress/conf.mk
make[3]: execvp: /bin/bash: Argument list too long
