Build errors incorporating libc

[Bob Stewart]

I'm building with 13.11 on an ARM platform. I've done a make prepare in 
libports for the libc package. The build fails during in the library  
creation on a "No rule to make target `_setjmp.o' " error ---
Snippet of the build log is:
   .
   .
   .
   Library libc-string
   Library init_pd_args
     MERGE    libc-string.lib.a
   Library libc-stdlib
     MERGE    libc-stdlib.lib.a

     MERGE    libc-locale.lib.a
   Library libc-stdio

   Library libc-setjmp

   Library ldso-startup

What am I missing?

Thanks,
