Environment variables "pollute" the build environment of packages and can affect their output. This change results in the removal of some files from packages that were not meant to be packaged. It also removes the need for a workaround in automake 1.10.3 to manually remove such files. Variables are now saved in an .env file for each system and included in scripts that need them using the dot operation.
