avr: Fix up avr_print_operand diagnostics [PR118991]

As can be seen in gcc/po/gcc.pot:
 #: config/avr/avr.cc:2754
 #, c-format
 msgid "bad I/O address 0x"
 msgstr ""

exgettext couldn't retrieve the whole format string in this case,
because it uses a macro in the middle.  output_operand_lossage
is c-format function though, so we can't use %wx to print HOST_WIDE_INT,
and HOST_WIDE_INT_PRINT_HEX_PURE is on some hosts %lx, on others %llx
and on others %I64x so isn't really translatable that way.

As Joseph mentioned in the PR, there is no easy way around this
but go through a temporary buffer, which the following patch does.

	PR translation/118991
	* config/avr/avr.cc (avr_print_operand): Print ival into
	a temporary buffer and use %s in output_operand_lossage to make
	the diagnostics translatable.
