I posit that this makes them easier to find.
The other day while working on the wchar_t patch, I had a bit of
trouble finding the DJGPP/go32 tdep bits. My initial reaction was
looking for a go32-specific tdep file, but there's none.
Confirmed that a --host=i586-pc-msdosdjgpp GDB still builds
successfully and includes the i386-go32-tdep.o object.
Confirmed that an --enable-targets=all build of GDB on x86-64
GNU/Linux includes the DJGPP/go32 bits too.
