:LIBELF_ARCH is defined based on the architecture libelf is being compiled
for. The file elf.c is pretty simple and LIBELF is conditionally defined in
this file:

https://git.rtems.org/rtems-tools/plain/rtemstoolkit/elftoolchain/libelf/_libelf_config.h

Since the definition of LIBARCH_ARCH is dependent on the host architecture,
what host are you compiling on?

Also the following command will show you all the gcc predefines. Is one of
them
for the architecture in the libelf_config.h file?

gcc -dM -E - </dev/null | less
