In addition:

The fault mixture is possible, if 'libgcc' is before to 'libm'.
It happens by default usage 'avr-g++'.
  If to specify 'libm' to the first all works correctly.
There is no replacement of separate modules 'libm' another's modules.
The addition 'libgcc' after 'libm' too is obligatory, for example
there is a reference to procedures of a prologue/epilogue functions
in 'libm'. However, connection 'libgcc' in the end is carried out
by default.
