(Responded in the bug as well...) I have a test version of the cross prelink
with the ARM HF patch available, as commit:
2cde4ff118b5244f5577d9bc585c1ee521740af0
To enable it, use the following in your local.conf:
SRCREV_pn-prelink = "2cde4ff118b5244f5577d9bc585c1ee521740af0"
If this works for you, I'll finish the patch and submit the changes.
