Description
This is an updated and (hopefully) complete version of patch #1550165 saving all the environment variables documented on the configure help. I'll revive a question from the original tracker item: should make fail if config.mk is missing? (just reconfiguring if it was properly configured before)
Ticket imported from: #1826459. Ticket imported from: patches/849.

I prefer the 2nd patch, i.e. that "make" fails with an error if config.mk is missing.
One small caveat, though: This patch will produce incorrect results if the user has never run the "new" configure. In particular, in that case SAVE_CONFIGFLAGS won't be set. So, instead of checking for BACKENDS in Makefile, I'd check for SAVE_CONFIGFLAGS. That seems to be more logical anyway. Or is there a specific reasons you check for BACKENDS?

My first approach was to check for SAVE_CONFIGFLAGS, but ifndef interprets it's undefined if it's empty, so if you called configure with no parameters it acted like you had no config.mk. I chose BACKEND because it always has a value, you can't assure any of the environment variables will be always set. Should we add a new always-set variable just for this? (SAVED_ENV=1?)

Hmmm, I see. So, maybe we should do it that way, i.e. added a SAVED_ENV:=1 or so. Or maybe call it CONFIG_MAK_IS_PRESENT :-)
Also, shouldn't we rename SAVE_CONFIGFLAGS to SAVED_CONFIGFLAGS?
Finally: Eugene, anything else to remark before we commit this? :)
