Thanks for that, I'll get started on merging it in.

To make use of VFP compiled shared libraries, it looks like we need to
install them along side the soft float versions, perhaps in a vfp
directory. The dynamic linker will then load the correct version
according to the flags stored in the ELF header of the executable
(which I think does indicate the type of FP system used). I'll look into
that too.

Thanks,
Lee.
