Subject: [PATCH] Make the build system work on macOS

The original file has extension `.F90`, the generated file changes the
extension to `.f90`, which works on Linux. However on macOS due to the
case-preserving filesystem it fails. The fix is to rename the generated file,
then it works on both Linux and macOS.
