Tian,

  The problem is that there is a restriction in the top level configure.in that prevents building
target-newlib and target-libgloss for sparc-*-sunos4* (it adds them to the noconfigdirs list). 
There is code in newlib to handle the configuration but it likely hasn't been tested because of the
top level restriction which has been in place since 1996.  To get around the problem, I would advise
you to delete your build tree and either reconfigure with --with-newlib added as a configuration
option or else apply the patch I am attaching and then reconfigure.
