[OE-core] Recipe specific sysroots: New failure to compile Go

[Kristian Amlie]

After the new feature, recipe specific sysroots, was added, I'm facing
the following compile error when compiling Go:

-------------------------------------------

-----------------------------------------------

Note in particular the "readsym out of sync", which appears to be the
heart of the problem.

Using git bisect I have verified that it is the commit
9107d6ca144ac1f6169830dee25dae2dad775333, the introduction of recipe
specific sysroots, that breaks the build. However, I cannot see an
obvious link between the two, the error looks very internal to Go. Any
clue what's going on?
