with Brian's kernel support for i386 debug registers. This makes
watchpoints actually usable for real-life problems. Note: you can
only set watchpoints on 1-, 2- or 4-byte locations, gdb automatically
falls back to [sloooow] software watchpoints when attempting to use
them on variables which don't fit into this category. To circumvent
this, one can use the following hack:
watch *(int *)0x<some address>
David O'Brien is IMHO considering to get this fully integrated into the
official GDB, but as long as we've got the i386/* files sitting around
in our private FreeBSD tree here, the feature can now be tested more
extensively, so i'm committing this for the time being.
This work has been done in order to debug a tix toolkit problem, thus
it has been sponsored by teh Deutsche Post AG.

libraries in LDADD so that `make checkdpadd' doesn't report non-errors.
Fixed some style bugs (the usual ones for DPADD and LDADD, and misformatting
of $FreeBSD$).
The target machine is represented by TARGET_ARCH. MACHINE_ARCH always
represents the host machine. When TARGET_ARCH is not defined, it is
assumed to be equal to MACHINE_ARCH. This means that we're building a
native toolset by default. We're creating cross-compilation tools when
MACHINE_ARCH != TARGET_ARCH.
TARGET_ARCH is defined when building binutils as part of the bootstrap
build and is set to reflect the architecture we're currently cross-
building. With this change binutils is ready for cross-building.
All Makefiles now use MACHINE_ARCH for the target architecture.
Unification is required for cross-building.

fixed typo: MACHINDE -> MACHINE_ARCH
tidy up the logic that works out which sub-directories to build.
The new directories with freebsdelf suffixes now have freebsd suffixes
after a repo move by Peter at the request of David O'Brien.
directory to /usr/cross/${MACHINE_ARCH}-freebsdelf/usr/lib so that
the cross tools behave the same way that the host versions do. When
building cross tools, Cygnus doesn't set the default library directory.
This doesn't suit FreeBSD IMHO.
Add WinNT emulation support too. You only get this if you've set
BINUTILSDISTDIR because the contrib/binutils repository doesn't
contain the required sources.

gas for i386 targeted to NT for those (like me) who have to do work
targeted to NT, but can't stand actually looking at it all day long.
I cross build apps on FreeBSD and just run them on NT later. Life is
better that way.
