So adopt the solution you have used in the past with other environment 
variable using patches that you have proposed - do not apply them to the 
official binutils sources, but do apply them to your own, 
tested-for-linux releases.  Then the binutils maintainers for the 
various different Linux distributions can choose, if they so wish, and 
if they use your binutils, to remove the patch before releasing the 
binutils to their public.
