The --enable-sim-hostendian flag was purely so people had an escape route
for when cross-compiling. This is because historically, AC_C_BIGENDIAN
did not work in those cases. That was fixed a while ago though, so we can
require that macro everywhere now and simplify a good bit of code.
This was done for all the other ports years ago, so catch ppc up.
The compiler/C library should produce reasonable code for htonl/ntohl,
and at least glibc tries pretty hard to always produce good code for
them. This logic only had support for 32-bit x86 systems anymore, and
it's unlikely people were even opting into this, so drop it all.
* sim-endian.h: Don't have parameters on macro definitions which
are simply renaming functions, to permit use of XCONCAT2 in both
the macro name and the arguments in a use of such a definition.
In sim/ppc:
