setup-environment-internal: print sstate cache info

[igoropaniuk]

1. Drop LMP_VERSION_CACHE_DEV, and let user define LMP_VERSION_CACHE explicitly with the value he needs. This helps to avoid issues when both LMP_VERSION_CACHE and LMP_VERSION_CACHE_DEV are defined in the environment, and leads to unexpected results.
2. Print version of LMP_VERSION_CACHE if it's set. Example: LMP state cache is enabled:
   LMP_VERSION_CACHE = 90
   SSTATE remote url = https://storage.googleapis.com/lmp-cache/v90-sstate-cache

I like the second part, but I'd keep the LMP_VERSION_CACHE_DEV as I, especially, use it in my local dev env. If LMP_VERSION_CACHE_DEV is unset, the behavior of the code is straight.

Its a bit ugly but the better option to use the dev cache locally is

unset LMP_VERSION_CACHE
export LMP_VERSION_CACHE_DEV=

This also works but remember to always run . setup-environment in a new shell.

echo "LMP_VERSION_CACHE_DEV=" >> ~/.bashrc

[quaresmajose]

soon I will try to remove this version and make it version agnostic, so it just works

SSTATE_MIRRORS ??= "file://.* https://storage.googleapis.com/lmp-cache/sstate-cache/PATH"

I have my own super-script around setup-environment with export LMP_VERSION_CACHE_DEV=1. Always :)

I have also one mega helper to configure MACHINE, DISTRO and build folder for each combination and of course with:

unset LMP_VERSION_CACHE
export LMP_VERSION_CACHE_DEV=
