[Bug fortran/34187] New: BIND(C): Public generic with private bind(c) specific does not use bind(C) name

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

As reported by Chris:
For the following code, the bind(C) is ignored when calling the private
specific subroutine "test" via calling the generic procedure "gen".
Result: The procedure "test_" is called and the linker complains.

If one makes "test" public, it works. As -fdump-parse-tree shows (after
applying the fixes from PR34186), in "main" "test" has the "bind(c)" attribute.

subroutine test() bind(c)
end subroutine test

module mod
  private
  public :: gen
  interface gen
     subroutine test() bind(c)
     end subroutine test
  end interface gen
end module mod

program main
  use mod
  call gen
end program main
