Sorry, patch is here:
uclibc.org/~aldot/uClibc/uClibc-0.9.29-optional-features.01p3.diff

As said, i've dropped the syscall-stubs for now and just added
config-knobs for stuff that should be optional.
Allnoconfig (with termios support turned on since this is not yet
finished) gives:

   text	   data	    bss	    dec	    hex	filename
  78553	    648	   9192	  88393	  15949	lib/libuClibc-0.9.29.so

Which starts to be ok for me.
TODOs: - fix turning off or give up on termios
       - make sure that IPv6-only works.
