[OE-core] [PATCH] default-distrovars: Clean up gcc license issues

[Richard Purdie]

There are several entries here which are not needed with the
modern license handling code:

gcc-source - moved to direct handling in base.bbclass
             (due to version appended to the name)
libgcc - Listed as GPLv3 exception for its packages
libgcc-initial - Listed as GPLv3 exception
gcc-runtime - Indivisual packages listed as GPLv3 exception where appropriate
