I see the same configure outputs if don't use the if I don't use the
--without-m17n-flt configure option.

But the compiling will fail with the error reported here:

/usr/bin/ld: 
/usr/lib/gcc/x86_64-linux-gnu/10/../../../x86_64-linux-gnu/libm17n-core.a(mtext-wseg.o):

But I can't compile emacs successfully even with these libraries
installed as shown below if I don't use the  --without-m17n-flt
configure option.
