bootstrap 5.4.0 fails in stage 3 with missing-objcopy: command not found

[Dennis Clarke]

Dear GCC'ers :

     I would like to think I am making progress with boot strapping
GCC 5.4.0 but I seem to keep hitting issues in stage 2 and then later
in stage 3. I think any failure within stage 3 must be a bug. Otherwise
how could we have possibly gotten past stage 2 of bootstrap to ever
arrive in stage 3 ?

     So I am seeing this in stage 3 :

Very strange that there is some sort of objcopy being looked for?  This
is not a linux server and there is no GNU binutils available. I don't
even know if the GNU binutils work at all on a Solaris 10 server.

So any hints from anyone on this ?
