sys-firmware/ipxe-1.0.0_p20130225 fails to build with gcc-4.8.
With stable gcc it builds fine. The error seems to differ from the one in bug 462898.

For gcc 4.8, please use ipxe-1.0.0_p20130624 which is in the tree already and report if that doesn't work for you.

I see the following error on hardened ~amd64 with gcc-4.8.1 for ipxe-1.0.0_p20130624:

You're really missing a bunch of context from this since the gcc line prior to the error is building memmap.c, but the error you are having is with bios_console.c there's no telling what extra flags affected it. That being said, I would really be surprised if our hardened toolchain is able to produce working ROMs since I know iPXE, SeaBIOS, etc are sensitive to the toolchain.

Aw, got the wrong line, here comes the correct one:

  [BUILD] bin/bios_console.o
x86_64-pc-linux-gnu-gcc  -DARCH=i386 -DPLATFORM=pcbios -march=i386 -fomit-frame-pointer -fstrength-reduce -falign-jumps=1 -falign-loops=1 -falign-functions=1 -mpreferred-stack-boundary=2 -mregparm=3 -mrtd -freg-struct-return -m32 -fshort-wchar -Ui386 -Ulinux -DNVALGRIND -Iinclude -I. -Iarch/x86/include -Iarch/i386/include -Iarch/i386/include/pcbios -Os -g -ffreestanding -Wall -W -Wformat-nonliteral   -fno-stack-protector -fno-PIE -nopie -fno-dwarf2-cfi-asm -fno-exceptions  -fno-unwind-tables -fno-asynchronous-unwind-tables -Wno-address  -ffunction-sections -fdata-sections -include include/compiler.h   -DOBJECT=bios_console -c arch/i386/firmware/pcbios/bios_console.c -o bin/bios_console.o 

I merged ipxe with hardened-gcc-4.7.4 and just booted a virtual machine with kvm/qemu -- during the boot I saw the string ipxe, so I assume that it works ...
