Subject: PGI: Add support for Fortran with the Ninja generator

The PGI documentation says that `-Mpreprocess` "instructs the compiler
to perform cpp-like preprocessing on assembly and Fortran input source
files".  The `-E` flag causes the compiler to spit the result to stdout
instead of saving it to a file.
