[patches] DFP branch: Define _FPU_* macros to fix S/390 build.

["Andreas Krebbel" <krebbel@xxxxxxxxxxxxxxxxxx>]

Hello,

on DFP branch printf_fp.c is now including fpu_control.h and relies on
the _FPU_* macros to be defined for every platform.  This hasn't been
the case for S/390 so far what currently breaks the build of eglibc.

The attached patch fixes this by adding the necessary macros.

If you think it's ok to apply please do and I'll try to get this also
integrated into glibc (although there is no user of these macros
currently).

Bye,

-Andreas-

	* sysdeps/s390/fpu/fpu_control.h: Add definitions for the
	internally used macros for decoding the floating point control
	registers.
