 Ok, you have UnixWare7, but the binutils-2.9.1 configure shouldn't
know 'i586-unixware7' or anything like that... So which target name
you used for it? Or did you just let configure to guess the name or to
solve it itself?

 Probably you mean 'ld' (the command to link objects into
executables), not 'ln' (the command to make hard and symbolic links
between files)...

 So it built easily the binutils for some unknown target, but for
which one? What does your linker say with './ld --help' ?  Does it
list the '-Qy' option? Does it even say that it supports the UW7
native 'elf32-i386' format?

 Here are snapshots from the 'ld --help' output of a Linux/x86-target
linker (for the 'elf-i386' and 'a.out-i386-linux' formats) :

 Probably your 'ld' is now made for SVR3, i386-aout or something else
than the expected 'i586-sysv4' or 'i586-sysv5' target and it really
doesn't know the '-Qy' option...

 I remember that UW7 must be called so that it fits into the
'i[34567]86-*-sysv5*' templates in the configure-scripts for the GNU
tools, so using something like:

  ./configure --build=i586-sysv5 --host=i586-sysv5 --target=i586-sysv5

to configure (not any kind of guessing allowed) should be quite
foolproof... 

 If one lets configure to guess what a 'i586-unixware7.1' or something
like that is, the result may simply be a match with a
'i[34567]86-*-unix*' template, which can then be the name for a
SVR2/x86....
