PlatformIO espressif8266@4.2.0 linker error

[trysten]

Newest PlatformIO platform package will not build homie-esp8266 (on linux) with:

Current workaround is downgrading platform to platform = espressif8266@4.1.0

I don't know what this error is about. Yet. We need to lock platform version for stable because right now a new install from PlatformIO will not build.

Thanks for the workaround. I ran into the same problem, but didn't know how to solve it.
