Subject: Make sure the Fortran specifics have real(kind=16).

This brings the library to compile with all specific functions.
It also corrects the patsubst patterns so the right files
get the flags.

It was necessary to manually add -D__powerpc64__ because apparently
this is not set for Fortran.

libgfortran/ChangeLog:

	* Makefile.am: Correct files for compilation flags. Add
	-D__powerpc64__ for Fortran sources.  Get kinds.inc from
	grep of kinds.h and kinds-override.h.
	* Makefile.in: Regenerate.
	* config.h.in: Regenerate.
	* configure: Regenerate.
	* configure.ac: Add -mno-gnu-attribute to compile flags.
	* generated/_abs_c17.F90: Regenerate.
	* generated/_abs_r17.F90: Regenerate.
	* generated/_acos_r17.F90: Regenerate.
	* generated/_acosh_r17.F90: Regenerate.
	* generated/_aimag_c17.F90: Regenerate.
	* generated/_aint_r17.F90: Regenerate.
	* generated/_anint_r17.F90: Regenerate.
	* generated/_asin_r17.F90: Regenerate.
	* generated/_asinh_r17.F90: Regenerate.
	* generated/_atan2_r17.F90: Regenerate.
	* generated/_atan_r17.F90: Regenerate.
	* generated/_atanh_r17.F90: Regenerate.
	* generated/_conjg_c17.F90: Regenerate.
	* generated/_cos_c17.F90: Regenerate.
	* generated/_cos_r17.F90: Regenerate.
	* generated/_cosh_r17.F90: Regenerate.
	* generated/_dim_r17.F90: Regenerate.
	* generated/_exp_c17.F90: Regenerate.
	* generated/_exp_r17.F90: Regenerate.
	* generated/_log10_r17.F90: Regenerate.
	* generated/_log_c17.F90: Regenerate.
	* generated/_log_r17.F90: Regenerate.
	* generated/_mod_r17.F90: Regenerate.
	* generated/_sign_r17.F90: Regenerate.
	* generated/_sin_c17.F90: Regenerate.
	* generated/_sin_r17.F90: Regenerate.
	* generated/_sinh_r17.F90: Regenerate.
	* generated/_sqrt_c17.F90: Regenerate.
	* generated/_sqrt_r17.F90: Regenerate.
	* generated/_tan_r17.F90: Regenerate.
	* generated/_tanh_r17.F90: Regenerate.
	* kinds-override.h: Adjust to trunk.
	Change condition to single line so it can be grepped.
	* m4/specific.m4: Make sure that real=kind16 is used
	for _r17.F90 and _c17.F90 files.
	* m4/specific2.m4: Likewise.
