[yocto] prelink & mklibs problem

[Qiang Yu]

Thanks for your reply. I almost give up.

You mean that current yocto build doesn't support hard float ABI prelink,
and the prelink source code needs to
be modified to use ld-linux-armhf.so.3?

So this problem affect all armhf build of yocto, in other words prelink
doesn't work for yocto armhf at all now?

Regards,
Qiang
