FYI,
other directories (mips, arm, sh) use "embed.mt" for the cross debug .mt 
file.

   FYI,

   other directories (mips, arm, sh) use "embed.mt" for the cross
   debug .mt file.

And Alpha and SPARC use alpha.mt and sparc.mt.  The new i386.mt isn't
solely used for embedded and/or cross targets, hence the new, neutral
name.

You're reading too much into a name.  embed.mt is both os and 
_architecture_ netural.  The fact that it comes with certain 
implications is, well, unfortunate.

Is *.mt still needed?

Unfortunately, yes.  We do need a place to specify which *-tdep.o
files are needed, and we still have some tm-*.h files left.  There are
some issues with getting rid of the tm-*.h files:

* Including "solib.h".  We should probably move towards including it
  unconditionally.

* SOFUN_ADDRESS_MAYBE_MISSING; We've discussed it before, talking
  about enabling it unconditionally, but I chickened out doing just
  that.

* STATIC_TRANSFORM_NAME/IS_STATIC_TRANSFORM_NAME.

* Real-time signal stuff (QNX Neutrino, Lynx).

The rest is OS-specific junk that could go.

Anyway, it should be possible to build a single GDB that is able to
debug GNU/Linux, FreeBSD, NetBSD, OpenBSD and Solaris on both IA-32
and AMD64.
