install issue when configured with ; --program-suffix=-X.Y.Z

[Iain D Sandoe]

Hello,

on OSX10.5/OSX10.5:
I am trying to run several versions of gcc in parallel (and also not  
to trample on the vendor-supplied one).
So I am building with --enable-version-specific-runtime-libs and  
using fully qualified version numbers (X.Y.Z)

When configuring with the following options

VERS=`cat /path/to/gcc-source/gcc/BASE-VER`

....
                         --enable-version-specific-runtime-libs \
                         --program-suffix=-$VERS \

I notice that the "target-apple-darwinZ-gcc-VERS" never appears  
(although the native gcc-VERS does).

this seems to be due to the following lines in gcc/Makefile.in

     install-driver: installdirs xgcc$(exeext)
         -rm -f $(DESTDIR)$(bindir)/$(GCC_INSTALL_NAME)$(exeext)
         -$(INSTALL_PROGRAM) xgcc$(exeext) $(DESTDIR)$(bindir)/$ 
(GCC_INSTALL_NAME)$(exeext)
aaa>      -rm -f $(DESTDIR)$(bindir)/$(target_noncanonical)-gcc-$ 
(version)$(exeext)
bbb>       -( cd $(DESTDIR)$(bindir) && \
          $(LN) $(GCC_INSTALL_NAME)$(exeext) $(target_noncanonical)- 
gcc-$(version)$(exeext) )

since:
  $(DESTDIR)$(bindir)/$(GCC_INSTALL_NAME)$(exeext) == $(DESTDIR)$ 
(bindir)/$(target_noncanonical)-gcc-$(version)$(exeext)

line aaaa> deletes the just-installed tool and then bbb> hard links  
to a non-existent file?

=== If this is a real bug ( and not a misunderstanding of naming  
systems on my part )

.... the following patch fixes it for me:
