Chris Manchester 942b77d16c Bug 1294803 - Move MOZ_SYSTEM_FFI to moz.configure in preparation for moving libffi to our build system. r=glandium
This patch introduces a small change in behavior: we now unconditionally
require libffi > 3.0.9 when using system ffi, rather than accepting 3.0.9
when using GCC, as 3.0.10 was released 5 years ago, and should be widely
available.
