Configuration: Checking that C and Fortran compilers work
Until now, we were just checking for the existance of a C and Fortran compiler. But it can happen that even if they exist, they don't operate properly, for example see some errors that have been reported until now in P.S. (both on different macOS systems). But finding this source after the programs have started is frustrating for the user. With this commit, before we start building anything, we'll check these two compilers with a simple program and see if they can indeed compile, and if their compiled program can run. If it doesn't work an elaborate error message is printed to help the users navigate to a solution. Also, the building of `flock' within `configure.sh' has been moved just before calling `basic.mk'. This was done so any warning/error message is printed before actually building anything. This fixes bug #56715. P.S. The error messages: C compiler ---------- conftest.c:9:19: fatal error: stdio.h: No such file or directory ^ compilation terminated. ---------- Fortran compiler ---------------- dyld: Library not loaded: @rpath/libisl.10.dylib Referenced from: /path/to/anaconda2/gcc/libexec/gcc/x86_64-apple-darwin15.5.0/4.9.3/f951 Reason: image not found gfortran: internal compiler error: Abort trap: 6 ----------------
