Even gas (the GNU assembler, here also known as avr-as) does:

$ avr-as -al=/dev/stdout -o /dev/null
.data
.byte   0b11110000
^D
GAS LISTING                     page 1


   1                    .data
   2 0000 F0            .byte 0b11110000

Anyway, accepting binary constants would be a worthwhile addition to
gcc, IMHO.  However, this cannot be made by the avr-gcc folks, it must
become a generally accepted gcc item.
