Send the -M switch to ld, get the link map to see who is calling what.  You
can add it to the dxegen command line.

The original emu387.dxe builds only used _write for some debugging messages
you should never see unless there were bugs.  If we are pulling in the 
version of _write from the library it should only be if we are referencing
a different symbol in the same _write module somewhere else.
