Cross builds of DF on FreeBSD 4.x broke a couple of days ago (~ April 5th)

cc1: Invalid option `-fno-stack-protector'
*** Error code 1


-fno-stack-protector is used sucessfully elsewhere in the build, so
I'm betting the specification of "PATH=/usr/bin:..." is causing grief
because the build is picking up the native compiler and not the cross
compiler which does support the above option. That said, I wasn't sure
whether the problem is using the native compiler or the compiler
option (or something completely different).
