Outdated support for Fortran, probable.

Whenever trying to compile a program, an error like below would show up.

```
c:/mingw/bin/../lib/gcc/mingw32/8.2.0/../../../../mingw32/bin/ld.exe: cannot open output file /tmp/f90.out: No such file or directory
collect2.exe: error: ld returned 1 exit status
[Finished in 0.376s]
```

I have tried in my two computers which gives the same results (both are Windows 10, although one is Home and the another, Pro.)

No errors showed when compiled through non-atom IDE (e.g. input "gfortran test.f in CMD")

Atom version: 1.40.1
Package version: 3.18.1
