FLASHER and FFLAGS are evaluated by the main Makefile.include or by file included by it. Their value does not need to be exported. This will also prevent evaluating 'PORT' for FFLAGS when not needed. Testing ------- `git diff --word-diff` only reports `export` being removed. `git show --stat` reports `84 insertions(+), 84 deletions(-)` Which is the same amount as lines that where matching `export[[:blank::]]\+VARIABLE`.
