[yocto] ICECC build failures?

[Takashi Matsuzawa]

Hello Yocto.

Recently I am trying icecc with bitbake and amd halfway satisfied.
Good to see batch of my compilation jobs consumed by my build machines on icemon
is not bad.

However, I can see my builds fail in certain condition eveytime and
wonder if it is a known issue and a workaround exists?

Symptom is the follows.

1) Using x86_64 build host and build machies.  All of them are running
Ubutnu 16.04.
2) My image is based on Fido (18.0).
3) I am just doing INHERIT += "icecc" and the jobs are shared with
build machines correctly.
4) x86 (genericx86) build is OK with and without icecee.
5) imx (sabre6qauto) build is OK without icecc, but NG (fails) with icecc.

The following is the failure log.
It says relocation record error during linkage.  I googled for a while
and learned similar error could be seen if there is binutils (libtool)
version mistmatch.

Maybe a) the host-provided native toolchain and b) yocto-provided
native/cross toolchain have version mismatch?  But I do not see this
error when I am not using icecc.  I just think if it is OK without
icecc, the same should be expected even if I use icecc (it just runs
the same toolchain on different PCs?)
