Would it be sensible to request binutils libraries to expand SONAME to include
the bits that influence ABI?

For example to change
    libbfd.so -> libbfd-2.30.0.so
to something like
    libbfd.so -> libbfd-2.30.0-64-bit-bfd.so

That way when user rebuilds binutils with different flags they would get the
errors about missing library instead of obscure SIGSEGV.
