Log: More ARM EABI object attributes in binutils. This adds support to binutils to include the Unaligned Access and Floating-point Half-precision attributes. the former marks ELF objects that may access ARMv6 style unaligned data, the latter that the binary uses the VFPv3/Advanced SIMD half-precision extension. These may be emmitted by clang so it's best to print a warning when the linker hits one of them.
