configure: Do --update check earlier.

Browse Source 
Previously we initialized variables and ran a few $CC tests first
(which was what the old version of --update needed.) Now, we can do it
almost immediately after the script begins.

Spotted by running --update on a GCCless system (as the $CC tests
gave warning messages due to no GCC, while CC= was set in --update
environs.)
