# SRCVERSION is the main kernel version, e.g. <version>.<patchlevel>.0.
# PKGVERSION is similar to make kernelrelease, but reimplemented, since it requires setting up the build (and all tags).
# e.g. SRCVERSION -> 4.9.0, PKGVERSION -> 4.9.47-530-g244b81e58a54, which leads to
#      linux-4.9.0-qcomlt (4.9.47-530-g244b81e58a54-99)
