gcc: xtensa: fix fprintf format specifiers

Browse Source 
HOST_WIDE_INT may not be long as assumed in print_operand and
xtensa_emit_call. Use HOST_WIDE_INT_PRINT_DEC/HOST_WIDE_INT_PRINT_HEX
format strings instead of %ld/0x%lx. This fixes incorrect assembly code
generation by the compiler running on armhf host.

	* config/xtensa/xtensa.c (xtensa_emit_call): Use
	HOST_WIDE_INT_PRINT_HEX instead of 0x%lx format string.
	(print_operand): Use HOST_WIDE_INT_PRINT_DEC instead of %ld
	format string.
