Not easily, without changes to Automake.

The issue is a bit different.  If you intend your project to be portable
to non-GNU compilers, then you may need this.  For example for some AIX 
compiler drivers (e.g., xlf95 for compiling a file named *.F90), and I
think maybe for Intel ifort as well.

Automake-1.10 support in those cases is incomplete: you will have to
override the inference rules in that case.  I intend to fix this soon.
