libebl.h is an internal elfutils header that should only be used when
hacking on a elfutils backend. It isn't a supported interface and might
horribly break between (minor) elfutils releases.
It seems to be used only for the following hack in abg-dwarf-reader.cc
to get a string representing of the architecture of the current ELF
elf_architecture_ = ebl_backend_name(ebl_openbackend(elf_handle()));
All this really does is map the EM_ constant found in the ELF ehdr to an
(internal) name for for the elfutils backend for that machine
Please don't use ebl directly, it really isn't meant to provide a
interface outside internal elfutils development purposes.
There isn't really a good way to map EM_ values to machine architecture
names. I am afraid you will have to write something yourself using the
comments in elf.h describing each EM_ constant. Or use the descriptions
from the gabi spec:
