Versions: SDK & XS are empty when building with mcconfig

[rwaldron]

rwaldron in ~/clonez/moddable/examples/commodetto/clock on public*
$ mcconfig -d -m -p esp
# xsc main.xsb
# xsl modules
# cc mc.xs.c (slots in flash)
# ld main.bin
# Versions
#  SDK:
#  XS:

Those values are derived via:

ARDUINO_ROOT ?= $(ESP_BASE)/esp8266-2.3.0
...
git_description = $(shell git -C  $(1) describe --tags --always --dirty 2>/dev/null)
SRC_GIT_VERSION = $(call git_description,$(ESP_BASE)/sources)
ESP_GIT_VERSION = $(call git_description,$(ARDUINO_ROOT))

ARDUINO_ROOT is not a git repo ;) That directory comes from step 6:

6. Download the ESP8266 core for Arduino repository. Copy the extracted esp8266-2.3.0 folder into your ~/esp directory

That link is for a release zip, which doesn't include .git

SRC_GIT_VERSION comes from:

$(ESP_BASE)/sources

Which I'm guessing previously existed, but no longer does. I've written a patch to follow
