tools infinite loop

[Cliff Wright <cliff%snipe444.org@localhost>]

I was just building devel/patch from a pkgsrc tar of 4/24/06 on a Linux
BusyBox based system. I ran in to a problem with the tools created in
work/.tools/bin. For instance the echo program is using a non full path
echo to send info to the .work.log. The path is set to have work/.tools/bin
early to pick up the special echo in that directory, but since that tools
echo also makes use of itself their is an infinite loop. Moving the directory 
in the path variable would not work as we want to use the tools in the tools 
directory. I could modify
pkgsrc/mk/tools/tools.Linux.mk, but this has not changed for a while,
so I wonder where else the problem could be?
