>Description:
pkgsrc/mk/wrapper/transform-sunpro-cc (GCC wrapper for SunPRO compiler) need to 
handle options for 64bit environment.

We cannot build some applications in pkgsrc with SunPRO compiler (Sun C 5.7 
2005/01/07) with 64bit options. We define following options on mk.conf.

----
PKGSRC_COMPILER=sunpro
CFLAGS=-xtarget=ultra -xarch=v9
CXXFLAGS=-xtarget=ultra -xarch=v9
LDFLAGS=-xtarget=ultra -xarch=v9
----

>How-To-Repeat:
build lang/perl with following option.

----
PKGSRC_COMPILER=sunpro
CFLAGS=-xtarget=ultra -xarch=v9
CXXFLAGS=-xtarget=ultra -xarch=v9
LDFLAGS=-xtarget=ultra -xarch=v9
----
>Fix:
At least, transform-sunpro-cc need to handle -m64 option. We can avoid this 
problem with appending following function to transform-sunpro-cc.
----

# SunPro needs -xarch=generic64 for selecting 64bits archtecture.

-m64)
        arg="-xarch=generic64"
        msg_log $wrapperlog "   (transform-sunpro-cc) to: $arg"
        addtocache=yes
        ;;

Of cource, we should also handle "-mcpu=*" option. But I don't know how to 
handle this to make a best solution.
