Upstream's OPUS_ARM_INLINE_ASM means any ARM with inline assembly, with OPUS_ARM_INLINE_EDSP layered on top for ARMv5E. config.h instead defines exactly one of them per core, so the names read as broader than they are, and code added ARM_ARCH tests beside them to pin the scope down. Renamed to OPUS_ARM_ASM_ARMV4_ONLY and OPUS_ARM_ASM_ARMV5E_AND_LATER throughout celt and silk, upstream files included; README.rockbox records it for the next libopus sync. No code change: opus.elf disassembly and section sizes are identical before and after on ARMv4 (e200v1), ARMv5E (Clip+) and ARMv6 (iPod Nano 4G).
