[PATCH] Fix handling of Tag_ABI_HardFP_use for ARM

[Nick Clifton]

Hi Jie,

> This patch sets Tag_ABI_HardFP_use to SP when a single precision FPU is
> selected.
>
> It also fixes the merge of Tag_ABI_HardFP_use. Currently,
> Tag_ABI_HardFP_use is not treated as (SP & DP) when it's zero and
> Tag_VFP_arch != 0. This patch changes it to conform to the documentation.

Approved and applied.

Cheers
