You have [meta-oe] in your subject, I believe you are after just
oe-core with this patch correct?

Epiphany is in upstream binutils with the matching ID,
https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=include/elf/common.h;h=25cfef2d6b1ae8e3f976f1e55576d0fbaff79027;hb=HEAD#l408

I assume 'e-os' is short hand for 'epiphany-os'?

Is there are reason for using e-os? I noticed in your layer that your
toolchains are actually target os 'elf' (e.g. epiphany-elf-gcc), in
which case it should be 'elf' that goes into the TARGET_OS variable.
This might be the reason for the issues that you see when compiling?
