unzip: fix configure check for cross compilation

The original configure runs a generated binary to determine
features. This is not correct for cross compilation. So change
the runtime tests into compile-time tests to fix the issue.

+Subject: [PATCH] unix/configure: fix detection for cross compilation
+
+We're doing cross compilation, running a cross-compiled problem
+on host to detemine feature is not correct. So we change runtime
+check into compile-time check to detect the features.
