Gcc 4.9 is not dropped from Buildroot, it's still there in the current
Git master.

Getting U-Boot to build with gcc 5.x should just be a matter of
backporting a U-Boot patch. Can you try applying something
like ./roseapplepi/patches/uboot/0001-compiler-.h-sync-include-linux-compiler-.h-with-Linu.patch
to your U-Boot and see if it works ?

Thanks!
