You appear to be using a fairly old release (1.5.1), which I do not believe had support for the ARM64. We are currently supporting the 1.8 and recently released 2.0 release. uClibc has minimal support and it's hard to know what the actual failure you are seeing since the actual compile log is not included. If you can reproduce this with a newer version of the meta-data then create a new bug.
