My suspicion is that you are not using the buildtools-tarball with your OE
build, but Wind River Linux automatically uses this in an attempt to avoid host
incompatibilities with all of the random hosts our customers use.

To use the OE version of buildtools-tarball, you will have to build it, extract
it and then source the environment file.

f4dade8e meta/conf/bitbake.conf         (Ed Bartosh                2016-01-07
13:39:39 +0200 179)     hostperl-runtime-native \

These are newer then Wind River Linux 8, which is based on Yocto Project 2.0 /
Jethro which was released around Nov 2015.

You you look at Jethro you will see:

34927dfa meta/conf/bitbake.conf         (Richard Purdie          2007-12-18
15:04:06 +0000 174)     perl-native-runtime \
34927dfa meta/conf/bitbake.conf         (Richard Purdie          2007-12-18
15:04:06 +0000 175)     python-native-runtime \

So you are attempting to compare apples to oranges (master/morty/krogoth against
jethro.)
