Your gcc profile is a set of gcc specs and symlinks to a specific gcc
version, since you can have more than one. The error just means
gcc-config didn't get run properly before uninstalling your previous
version of gcc.

Run gcc-config to set your profile to the one you have listed:

# gcc-config 1

You will get the error every time you run gcc-config until you set a
valid profile; after that it should go away and builds should work again.
