OK.

I was using git master but I tried with pristine 2.8.8 and it works for me...

Almost the same for me (64 bits Linux Debian Wheezy).

I may have a wild guess, does your project enable Fortran language first?

that is in your main CMakeList.txt do you have

project(Whatever Fortran)

...

enable_language(C)
enable_language(CXX)
...

if it is the case could try enabling C language first?
i.e.
project(Whatever C)
...
enable_language(Fortran)
enable_language(CXX)


It looks like CMakeDetermineFortranCompiler.cmake may not setup
_CMAKE_TOOLCHAIN_PREFIX as C and C++ does.
