Yes, it should be LLVM_BINUTILS_BOOTSTRAP that's responsible, not
LLVM_BINUTILS. The former is only in main while LLVM_BINUTILS is also
in stable/15. The changes to support LLVM_BINUTILS BOOTSTRAP were
missing from the original LLVM_BINUTILS work; it was not intentional
that we continued to use ELF Tool Chain tools for the bootstrap.

We discovered this because another tool (i.e., libabigail) failed when
the standalone debug files _lacked_ program headers, and I believe
this is the expected state in the GNU tool / Linux distro world. I
presume Valgrind on Linux handles this somehow?
