log file of "testsdk"

Specify multilib as described in poky/meta-skeleton/conf/multilib-example2.conf:
Place in local.conf:

MACHINE = "qemux86-64"
require conf/multilib.conf
MULTILIBS = "multilib:libx32"
DEFAULTTUNE_virtclass-multilib-libx32 = "x86-64-x32"

also add 

USER_CLASSES += " testsdk "

run 

$ bitbake core-image-minimal 
$ bitbake core-image-minimal -c testsdk

The test fails (see the attached log).
The reason is the x32 meta-toolchain is not built correctly.
There are two issues:
CPP cannot find include files
CC cannot find libgcc
Comment 1 Juro Bystricky 2016-10-06 15:12:46 UTC 
correction to reproduce the problem:

run 

$ bitbake core-image-minimal -c populate_sdk
$ bitbake core-image-minimal -c testsdk
