Hi RP,

Yes, I do the test to build openssl-native from scratch, it requires 
extra 4 minutes

1. Use host perl
18 task
real    1m33.978s
user    0m0.728s
sys     0m0.080s

2. Use nativeperl
114 tasks
real    5m49.911s
user    0m1.372s
sys     0m0.140s

But for a image build, the cost is not much
(To exclude network affect, we assure all tarball/git exist in downloads)
But build a image from scratch:

time bitbake core-image-minimal

1. Use host perl
NOTE: Tasks Summary: Attempted 1655 tasks of which 5 didn't need to be 
rerun and all succeeded.

real    28m29.625s
user    0m7.296s
sys     0m0.988s

2. Use native perl
NOTE: Tasks Summary: Attempted 1655 tasks of which 5 didn't need to be 
rerun and all succeeded.

real    28m42.619s
user    0m7.496s
sys     0m0.952s


As upstream said, it indeed require specific PERL version

`If you are building OpenSSL 1.1.0 and above, then you will also need 
PERL 5.10 or high'

https://wiki.openssl.org/index.php/Compilation_and_Installation

And I found at least PERL 5.16.3 not work for OpenSSL 1.1.1

Or add a perl version detecting in insane check? We should report a lowest
workable perl version number when detect failed. But we may update the 
version
number in insane check when openssl is upgraded.
