[PATCH] Fix PR 40800, failure to build i386-unknown-freebsd8.0

[Jerry Quinn]

I was unaware that the stricter test was required for some platforms.  I
had pulled the test template from other configure scripts.

This fixes the problem on i386-unknown-freebsd8.0, and builds on
x86_64-unknown-linux-gnu.
