kbuild: Fix debugging info generation for .S files
Change the debuging info generation flag in KBUILD_AFLAGS from '-gdwarf-2' to '-Wa,--gdwarf-2'. This will properly generate the debugging info for .S files when CONFIG_DEBUG_INFO=y. It seems current gcc does not pass a '--gdwarf-2' option on to the assembler when '-gdwarf-2' is on its command line (note the differece in the gcc and as flags). This change provides the correct assembler flag to gcc, and so does not rely on gcc to emit a flag for the assembler.
