[ECOS] build problem with 2.0

[Grant Edwards <grante at visi dot com>]

I'm stumped.

I moved my serial driver from an older snapshot to 2.0, and it
doesn't build properly.  When I do a make, it only compiles
three of the five source files then complains it doesn't know
how to make the other object files, and I can't figure out why.

The same CDL file worked fine with an older eCos snapshot, and
it looks like this:

  cdl_package CYGPKG_IO_NSERIAL {
  [...]
         compile       -library=libextras.a serial.c haldiag.c
      
  [...]
         cdl_component CYGPKG_IO_SERIAL_DMRTS {
            flavor        bool
            active_if     CYGPKG_IO_NSERIAL
            default_value 1
  [...]
            compile       -library=libextras.a dmrts.c aiopic.c uart4530.c
  [...]
      }
  }

So, 5 source files should get compiled and the resultant object
files put into libextras.a: serial.c haldiag.c dmrts.c aiopic.c
uart4530.c

The error at the end of the build is:

  make[1]: *** No rule to make target src/aiopic.o.d', needed by libextras.a.stamp'.  Stop.
  make[1]: Leaving directory /home/devicemaster/ecosnew/io/nserial/current'
  make: *** [build] Error 2


Both files from the first "compile" directive get compiled, but
only the first one from the second "compile" directive gets
compiled.

In the makefile, the COMPILE variable contains all 5 source
files, but only the first 3 get compiled, then the error about
not knowing how to build the 4th.
