lli -force-interpreter Error

When I try to run this command

lli -force-interpreter file.ll

I have this error

LLVM ERROR: Tried to execute an unknown external function: posix_memalign

Also, when I search for this error I found this link:

http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20130923/188702.html

Also, I tried to recompile LLVM using --enable-libffi, then it gives me the same error

How could I solve this problem?

I found that .ll file has posix_memalign . Could I replace it ??
