The file config/i386/tm-i386v42mp.h contained only definitions for a
native Unixware GDB. I moved the relevant bits over to
config/i386/nm-i386v42mp.h and got rid of the file.
Committed.

except the inclusion of "i386/tm-i386.h", to...
* config/i386/nm-i386v42mp.h: ...here.
* config/i386/i386v42mp.mt (TM_FILE): Set to tm-i386.h.
