[yocto] [meta-cloud-services][PATCH] erlang: skip the host library path check to fix cross-compile issue

[Bruce Ashfield]

Thanks for the patch!

A couple of requests.

Can you list the compile issue here ? i.e. just a bit of the error
message showing it clearly. Someone else searching for a problem will
find it very useful!

This should be a separate patch. Can you split the commit and send
this as a two part series ?
