Modify the dconfig.h header file so that libdecnumber code integrates QEMU
configuration. Specifically:
- the WORDS_BIGENDIAN preprocessor macro is used in libdecnumber code to
determines endianness. It is derived from the existing QEMU macro
HOST_WORDS_BIGENDIAN which is defined in config-host.h.
- the DECPUN macro determines the number of decimal digits (aka declets) per
unit (byte). This is 3 for PowerPC DFP.
