 You do not need to define such variables by hand.  In a buildworld
 log on my Ultra5, the line is as follows and the buildworld works fine:

 cc -O -pipe -I. -static -DGENERATOR_FILE \
  -DTARGET_CPU_DEFAULT=TARGET_CPU_ultrasparc -DIN_GCC -DHAVE_CONFIG_H \
  -DPREFIX=\"/usr\" -I/usr/obj/usr/src/gnu/usr.bin/cc/cc_tools/../cc_tools \
  -I/usr/src/gnu/usr.bin/cc/cc_tools/../cc_tools \
  -I/usr/src/gnu/usr.bin/cc/cc_tools/../../../../contrib/gcc \
  -I/usr/src/gnu/usr.bin/cc/cc_tools/../../../../contrib/gcc/config \
  -I/usr/obj/usr/src/sparc64/legacy/usr/include
  -c /usr/src/gnu/usr.bin/cc/cc_tools/../../../../contrib/gcc/gencheck.c
