Just try without custom-cflags.

And as per equery u grub:0 ->  - - custom-cflags : Build with user-specified CFLAGS (unsupported)


I'd say it could be invalid.

Or at least it could be:
sys-boot/grub:0[custom-cflags] is broken by default with gcc:4.8 because of -fstack-protector.

Thank you for that hint, switching off custom cflags indeed solved the problem.
