[OE-core] gcc errors while building core-image-sato-sdk

[Damian, Alexandru]

I guess the problem is no lmld, (skips over), Mihai says that

- library search path "/usr/lib/cmplrs/cc2.11" is unsafe for
cross-compilation

is the cause.


I'm unable to trace back the cc2.11 file name (path).



Let's take it bit by bit, we have two issues here.
1. - why the configure hangs from time to time (what is that c2.11 ??)

2. - why sometimes it triggers massive rebuild even if nothing is changed.

Regarding point 2, does anybody else sees it ?
