The JZ47xx and S5L87xx processor families used their own special defines (__ASSEMBLY__ and ASM respectively) in their CPU headers to check if they were included from an assembly source file. For GCC the standard seems to be __ASSEMBLER__, so check for that instead and remove the non-standard symbols. Being more consistent across platforms makes it easier to include cpu.h from cross-platform files (eg. plugin.lds). Change-Id: I282930cad34e1a2ff18166f3b4338548b34f4a49
