Fix info gathering in Makefile
- Fix info gathering in Makefile
Okay, I have no idea why, but if I store the output of the script in a
Makefile variable newlines disappear (or something, I don't know), but
we'll get the STABLE_BUILD_GIT_TAG
for all the variables ...
Well, now we call the script three times ¯_(ツ)_/¯.
