This took some digging, but I finally found a script from the Bad Old Days
which did exactly this.  Arguments to rsync were

  --rsync-path=/usr/local/bin/rsync                                         \
  --stats --archive --delete --compress            --update --times         \
  --exclude='#cvs.rfl.*' --exclude='#cvs.wfl.*' --exclude='#cvs.lock'       \
  --exclude='gcc/gcc/ada/' --exclude='gcc/gcc/ch/' --exclude='gcc/gcc/f/'   \
  --exclude='gcc/gcc/java/' --exclude='gcc/gcc/objc/'                       \
  --exclude='gcc/zlib/' --exclude='gcc/libchill/' --exclude='gcc/libf2c/'   \
  --exclude='gcc/libffi/' --exclude='gcc/libio/' --exclude='gcc/libjava/'   \
  --exclude='gcc/libobjc/' --exclude='gcc/libstdc++/'                       \
  --exclude='gcc/testsuite/g77.dg/' --exclude='gcc/testsuite/g77.f-torture/' \
  --exclude='gcc/testsuite/objc/' --exclude='gcc/testsuite/objc.dg/'        \

That will still get the C and C++ compilers, libstdc++-v3, and associated
testsuites.  From there, it's easy to remove the Java-associated directories
from the list above and get that language too.

'--compress' might actually do more harm than good these days, dunno.
