Subject: Issue with make -j4 when building in separate tree.

There seems to be a dependency problem when running
make with multiple jobs (-j4).

I am compiling 2.6.16.16 in a separate tree. I created
the tree with the command:

[greear@xeon-dt linux-2.6.dev]$ make O=~/kernel/2.6/linux-2.6.16.k6/ xconfig

Then tried to build with this command.

[greear@xeon-dt linux-2.6.16.k6]$ make -j4 bzImage modules
make -C /home/greear/git/linux-2.6.dev O=/home/greear/kernel/2.6/linux-2.6.16.k6 bzImage
make -C /home/greear/git/linux-2.6.dev O=/home/greear/kernel/2.6/linux-2.6.16.k6 modules
GEN /home/greear/kernel/2.6/linux-2.6.16.k6/Makefile

This error has existed at least since 2.6.13.

Thanks,
Ben
