I changed the LDFLAGS on the script to:
LDFLAGS="-Wl,-elf2flt -Wl,-move-rodata " \
LIBS="-L/home/nafi/uClinux-dist/lib/uClibc/lib -lc" \

and now I get a library file, but when I try to use it, I get a lot of 
'undefined reference to 'memcpy' , 'fopen',...

I think it is a problem with the libtool yet. I can see that when the 
libtool generates the library, it uses the LIBS parameter but it still 
does not use the LDFLAGS.

../libtool --mode=link m68k-elf-gcc -o libttf.la freetype.lo ftxkern.lo

And this last warning about _start symbol is really suspicious, isn´t 
it? Any idea?

Thank you,
