Re: forcing the linker to be a particular one (i.e. gold vs bfd)

Hi Vladimir,

  I am sorry but I am out of touch with this topic.  It seems to me 
that there are two solutions:

 1. Use gcc's -B command line switch to select a directory containing 
the desired linker, or more probably the desired collect2 or exec-tool 
script.

 2. Add a new GCC command line switch to allow the user to select a 
linker by name and then provide a mechanism for locating it.

Option 1 is easy and requires no changes, but as Matthias already 
pointed out, it only works if the user (or build mechanism) already 
knows where the linker(s) have been installed.

If I remember correctly my original patch implemented option 2 by adding 
some more logic to gcc/exec-tool.in.  I still think that this is the 
easiest solution.  It should mean no other changes to gcc or the 
binutils and it makes use of a linker wrapper mechanism that is already 
in place.

Cheers
  Nick
