[patch] i386-nto (QNX Neutrino) support

["Kris Warkentin" <kewarken at qnx dot com>]

In the interest of expediency, I removed the non-i386 things from debug.h
which I believe eliminates the portability issues.  These can be re-examined
later when I'm doing the mips/powerpc ports.

Most of this stuff has been gone over by Mark Kettenis fairly extensively (I
ran indent again Mark) and I hope that the debug.h issue was the last of
them.  I've attached a diff of the config files as well as all the
individual files.  I also included a tarball that can be extracted in the
gdb directory.

Thanks

Kris
