* config/rs6000/xcoff.h (XCOFF_CSECT_DEFAULT_ALIGNMENT_STR): New
internal macro. Default alignment factor for csect directives, chosen
to match what BIGGEST_ALIGNMENT allows.
(DATA_SECTION_ASM_OP): Use it.
* config/rs6000/rs6000.c
(rs6000_xcoff_output_readonly_section_asm_op):
Use XCOFF_CSECT_DEFAULT_ALIGNMENT_STR.
(rs6000_xcoff_output_readwrite_section_asm_op): Likewise.
