Title: sys-devel/kgcc64 removal on sparc
Author: Raúl Porcel <firstname.lastname@example.org>
sys-devel/kgcc64 is going to be removed from the sparc system package set
since the normal sys-devel/gcc can, since version 4.4, build 64bit kernels.
Until now, you had to use CONFIG_CROSS_COMPILE="sparc64-unknown-linux-gnu-"
in your kernel config, but with sys-devel/kgcc64 going away, you need to
remove that option from your kernel configuration.
