If one wishes to anchor the compiler toolchain tree somewhere other than /,
all one needs to do is set "TOOLS_PREFIX" to a different rooting.

anymore as building -CURRENT sources on 3-STABLE was the reason for the
previous revision adding this.
Note that since the GCC Project moved mkstemp.c from GCC's world to
libiberty, we no longer support building -CURRENT sources on non-FreeBSD
boxes unless that box has a very simular libc mix as FreeBSD.
__FreeBSD_version < 400004.
This allows -STABLE to build -CURRENT sources.
[mkstemps() was added to -current just before the version bump to 400004
(a matter of hours in this case), so the test is as exact as possible.]
