[patches] DFP branch: Make convert.h machine-independent

[Andreas Krebbel <krebbel@xxxxxxxxxxxxxxxxxx>]

Hello,

dfp/sysdeps/soft-dfp/convert.h currently uses power specific functions. 
 The attached patch replaces this with the generic versions of these 
functions.

I've just made sure that it compiles for S/390.
Could someone please test this on Power? Thanks.

Bye,

-Andreas-

	* dfp/sysdeps/soft-dfp/convert.h (DFP_TEST_EXCEPTIONS,
	DFP_CLEAR_EXCEPTIONS): Use machine-indepedent functions.
