[Committed] S/390 TPF: Fix target default flags

[Andreas Krebbel]

Hi,

when the S/390 back-end options were moved to s390.opt we forgot to
adjust the tpf default flags accordingly.

Done with the attached patch.

Committed to 4.3, 4.4 and mainline.

Bye,

-Andreas-

	* config/s390/tpf.h (TARGET_DEFAULT): Remove MASK_HARD_FLOAT and
	add MASK_HARD_DFP.

If you're maintaining the TPF target, could you add the stdint.h type 
configuration for it to GCC?  Of the OSes listed in 
<http://gcc.gnu.org/ml/gcc/2009-07/msg00625.html> as needing it added, I 
think only OpenBSD has so far had it added since then.

I'm not actually maintaining the TPF back-end. I just take care of it
since it is part of the s390 Linux back-end.  TPF does not use glibc
but they use the glibc stdint.h header so it should be correct to
simply use the glibc-stdint.h definitions.

Bye,
