 Well, the option used to select between 64-bit and 32-bit ELF for 
building 64-bit configurations.  I can see it has been changed from its 
original meaning and it now only controls whether "-mno-explicit-relocs" 
is passed to the compiler or not, which is sort of useless and certainly 
does not match the intent nor what the description says.  The 64-bit 
format is now used unconditionally and you can always pass such obscure 
options to the compiler on the make's command line, so instead of this fix 
I vote for complete removal of the BUILD_ELF64 option.
