Hmm...  Yes, rcall/rjmp is used in libgcc.S.  Though math functions are
bulky enough. And decimal float point in future...  Perhaps, it is a bug
which waits for the hour?

I am intented to replace it to XCALL/XJMP macroses.
Now it is a separate library, which size (.text) less than 4KB.  But as
in libc there were calls of float point, I am not assured, that the libm
will be always one piece. Earlier there were reasons of efficiency (the
quantity of intermodular communications is very great in libm), but
link-time (--relax) optimization now works.
