ChangeLog:

2019-02-26  Martin Liska  <mliska@suse.cz>

	* math/Makefile: Change location where math-vector-fortran.h is
	installed.
	* math/finclude/math-vector-fortran.h: Move from bits/math-vector-fortran.h.
	* sysdeps/x86/fpu/finclude/math-vector-fortran.h: Move
	from sysdeps/x86/fpu/bits/math-vector-fortran.h.
	* scripts/check-installed-headers.sh: Skip Fortran header files.
	* scripts/check-wrapper-headers.py: Likewise.
