From 42f7bbc1ce4913fe2c0bc76293c5445d31690f5d Mon Sep 17 00:00:00 2001

Subject: [PATCH] configure.ac: do not run conftest in case of cross
compilation
It'll give us nothing but error like below:
./conftest: cannot execute binary file: Exec format error
...
./configure: line 23950: test: -eq: unary operator expected
The version check only has effect on Apple systems. We'd better
avoid error like above when cross compilation.
Also, in case of cross compilation, instead of having the above
Exec format error and resulting in unaligned_cv_fail to yes, set
it directly to yes.
Upstream-Status: Submitted [https://github.com/appneta/tcpreplay/pull/849]
