Bootstrapping on Solaris 8: ar and ranlib

[Georg Schwarz <georg.schwarz%freenet.de@localhost>]

I bootstrapped pkgsrc Q2/09 on a freshly installed Solaris 8 system.  
Before doing so, I added gcc_small-3.3.2-sol8-sparc-local from  
sunfreeware.com.
I bootstrapped using CC=/usr/local/bin/gcc, which I also added to mk/ 
mk.conf.
Now that installation failed to build net/tnftp because it would not  
find ar and ranlib which are in /usr/ccs/bin. Sure, I could add that  
to my PATH, but I think there should be a way for pkgsrc to find it  
without doing so.
I added to etc/mk.conf:

CONFIGURE_ENV+=         RANLIB=/usr/ccs/bin/ranlib
CONFIGURE_ENV+=         AR=/usr/ccs/bin/ar
MAKE_ENV+=              RANLIB=/usr/ccs/bin/ranlib
MAKE_ENV+=              AR=/usr/ccs/bin/ar


this seems to do the trick, but probably it is not the cleanest of  
approaches.
Would it be possible to have something like TOOLS_PLATFORM.ar and  
TOOLS_PLATFORM.ranlib?
