does it build when you use a gcc version that's actually in the tree ?
Yes, GCC 5 builds it successfully.
I also got link errors with memtest86+ but slightly different. I put it here because I think they might have the same root cause (something to do with the gcc ABI change). The package merges with gcc-4.9.3 (stable) but not with gcc-5.4.0 (~amd64) and also not with gcc-6.2.0-r1 (hardened). This happened while I recompiled my install with gcc-5.4 and only 3 packages (including memtest86+) among 1379 failed to build. x86_64-pc-linux-gnu-ld --warn-constructors --warn-common -static -T memtest_shared.lds \ -o memtest_shared head.o reloc.o main.o test.o init.o lib.o patn.o screen_buffer.o config.o li nuxbios.o memsize.o pci.o controller.o random.o spd.o error.o dmi.o cpuid.o && \ x86_64-pc-linux-gnu-ld -shared -Bsymbolic -T memtest_shared.lds -o memtest_shared head.o reloc .o main.o test.o init.o lib.o patn.o screen_buffer.o config.o linuxbios.o memsize.o pci.o cont roller.o random.o spd.o error.o dmi.o cpuid.o lib.o: In function `__inb': lib.c:(.text+0x0): multiple definition of `__inb' init.o:init.c:(.text+0x0): first defined here lib.o: In function `__inbc': lib.c:(.text+0x10): multiple definition of `__inbc' init.o:init.c:(.text+0x10): first defined here [... lots of similar lines ...]
(In reply to Jérôme Borme from comment #4) your error messages imply you're not building the latest 5.01-r2
this bug should be fixed by: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=4a1ef46c041d7851ff0bb27ddb3bd321afebed8f the test.c & random.c files were missing -fno-stack-protector.
