re PR target/26427 (with -fsection-anchors with zero sized structs)
PR target/26427
* config/darwin.c (darwin_asm_output_anchor): Disable
-fsection-anchors on darwin for now.
* config/darwin.h (TARGET_ASM_OUTPUT_ANCHOR): Likewise.
* rs6000/rs6000.c (optimization_options): Likewise.
testsuite:
* gcc.dg/pr26427.c: Test to ensure that -fsection-anchors doesn't
produce bad code on darwin.
