it can be built via BINFORMAT=elf in the environment. Most likely
some of the directory defines such as STANDARD_EXEC_PREFIX will
change again soon, as we settle on the proper locations for the

using the ELF compiler, unless arrangements have been made for the
compiler to find the ELF assembler instead of the a.out assembler.
