>Description:
I tried to use the same driver program to compile both on Solaris 2.6 and on Solaris 8.  I separated the drivers and libraries with "--enable-version-specific-runtime-libs", and made a little script selecting the correct -b option.  I configured to use the native linker rather than the GNU one.

This fails.  Apparently the "-b MACHINE" flag is passed to the linker from "collect2".  That would make sense if I had the GNU linker installed, but not with the native linker.  (It does accept the -b flag, but it means something completely different and doesn't take any argument.)
>How-To-Repeat:
Create a minimal C file containing an empty main function:

  sundance> echo "main(){}" > x.c

Compile that, on a Solaris 8 system, with a Solaris 2.6 driver and the appropriate -b flag:

  sundance> gcc -b sparc-sun-solaris2.8 x.c -o x
  ld: fatal: file sparc-sun-solaris2.8: open failed: No such file or directory
  collect2: ld returned 1 exit status

Here follows the same command with -v flag, and -Wl,-v to see what collect2 does too.

sundance> gcc -b sparc-sun-solaris2.8 -v -Wl,-v x.c -o x
