Prefer MACHNE_CPUARCH to MACHINE_ARCH in most contexts where you want
to test of all the CPUs of a given family conform.

Build usr.bin/ with WARNS=6 by default.

Tweak the support for using ldd on 32-bit objects a bit further.

2008-08-01T21:52:41+00:00

Specifically, build a 32-bit /usr/bin/ldd32 on amd64 which handles 32-bit
objects.  Since it is a 32-bit binary, it can fork a child process which
can dlopen() a 32-bit shared library.  The current 32-bit support in ldd
can't do this because it does the dlopen() from a 64-bit process.  In order
to preserve an intuitive interface for users, the ldd binary automatically
execs /usr/bin/ldd32 for 32-bit objects.  The end result is that ldd on
amd64 now transparently handles 32-bit shared libraries in addition to
32-bit binaries.

doesn't work on the Alpha platform: machine/elf.h doesn't include
sys/elf32.h there.
