Wrong. This is NOT an old/new binutils issue, it's an ABI issue.
EABI toolchains set the low bit. Legacy ABI uses STT_ARM_TFUNC.
For an EABI system you need new *everything*.

I only care about EABI, so I've no personal objections to this.
However I suggest making it a hard error to mix Thumb and old-ABI.
