* i386.c (asm_output_function_prefix, load_pic_register):

Use ASM_GENERATE_INTERNAL_LABEL properly.
(output_pic_addr_const): Recognize %X to supress any PIC sym suffix.
(print_operand): Ignore it.
(load_pic_register): Use it for the got load call.
* i386.md (prologue_set_got, prologue_get_pc): Likewise.
(prologue_get_pc_and_set_got): Likewise.
* i386.h: Update print_operand docs.
