Can you check what options are being passed to the compiler
and the assembler, and check for .arch / .arch_extension directives
in the assembler input?

i.e.,

make V=1 CFLAGS_KERNEL='-v -save-temps' arch/arm/mach-omap2/sleep34xx.o

...and look at the output and the generated sleep34xx.s

Maybe the options being passed to the compiler/assembler are wrong
somewhere along the line.
