[i386] Add explicit ""aw", @nobits" declarations to stack sections As reported by Stefan, commit 13d09e6 ("[i386] Simplify linker script and standardise linker-defined symbol names") breaks gdb, readelf and associated utilities. This is caused by the .stack section overwriting a block in the middle of the .debug_info section (despite being included in the .bss.textdata section in the output file, which apparently has the correct attributes for a .bss section). Fixed by adding explicit flags and type to the stack section declaration. 2009-02-15 10:02:26 +00:00			`.section ".stack", "aw", @nobits`
