e58ffeb322 Remove all traces of __powerpc__ 
According to $GCC/gcc/config/rs6000/rs6000-c.c _ARCH_PPC is the
ubiquitous define which should be used to test whether gcc targets
PowerPC, on 64bit platforms _ARCH_PPC64 will be also defined.

e872aa811a softfloat-native: fix type of float_rounding_mode 
fegetround() and fesetround() are using an int type. Change the type of
float_rounding_mode and floatx80_rounding_precision in the float_status
structure for consistency.
