[Bug fortran/35707] New: Search /usr/local/include and /usr/include for .mod files

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Other compilers such as g95, NAG f95 and ifort also search /usr/local/include
and /usr/include for .mod files (and "INCLUDE"d files).

I think gfortran should do the same, especially since #include searches these
paths and "man gfortran"'s -Idir description implies #include and include
search the same directories.

g95 seems to use libcpp for reading almost all files and thus it searches also
in /usr/include (cpp_create_reader, cpp_read_main_file etc.). That way one
could also cpp-preprocess files included via "INCLUDE" rather than via
"#include".

The system include path is in the variable GCC_INCLUDE_DIR, which does not seem
to be used outside of cpp unless I missed something.
