Details:

The __mul[hs]i_const_10 functions are defined in assembly, but these symbols'
types are unknown ("NOTYPE") in ELF object.

Example:
$ avr-readelf -s ~/install/avr/lib/avrxmega3/libc.a | grep "_const_10"
     6: 00000000     0 NOTYPE  GLOBAL DEFAULT  UND __mulhi_const_10
     6: 00000000     0 NOTYPE  GLOBAL DEFAULT  UND __mulsi_const_10
     5: 00000000     0 NOTYPE  GLOBAL DEFAULT    4 __mulsi_const_10
     5: 00000000     0 NOTYPE  GLOBAL DEFAULT    4 __mulhi_const_10

The attached patch updates these functions type and also adds .size
attribute.
Output after applying this patch:
$ avr-readelf -s ~/install/avr/lib/avrxmega3/libc.a | grep "_const_10"
     6: 00000000     0 NOTYPE  GLOBAL DEFAULT  UND __mulhi_const_10
     6: 00000000     0 NOTYPE  GLOBAL DEFAULT  UND __mulsi_const_10
     5: 00000000    42 FUNC    GLOBAL DEFAULT    4 __mulsi_const_10
     5: 00000000    16 FUNC    GLOBAL DEFAULT    4 __mulhi_const_10
