* Makefile.common: do PLILST.nlffi (though this file isn't used...)
* Modernize the powerpc entry in signal-sysdep.h to use the
various _UC_MACHINE_ macros.
* mk.ppc-netbsd: don't pass an empty RANLIB variable, causing build failure.
Also make checksums of all the three arch-specific distfiles ("boxes"),
for sparc, x86 and ppc.
Bump PKGREVISION.
