Ah, I didn't realize before that you're cross-compiling.

It looks like your toolchain file may not set everything it needs to set.
Did you get this error with Trilinos 10.0?  Please also review this page:

This is the real problem that leads to the error message you get from
the TrilinosFortranMangling.cmake module.  I'm not familiar with this
version of Fortran mangling detection.  Hopefully one of the Trilinos
developers can jump in here.

This is the part that's implemented by CMake upstream.  It's working.
