You need to have two git trees: sound.git tree containing the complete
Linux kernel tree, and alsa-driver-build.git containing only the build
stub for external builds.

In the recent change, alsa-driver-build.git (or equivalent with
alsa-driver.git in alsa-project.org) contains only README in master
branch.  Checkout build branch instead.  Then you'll get the whole
build stuff in alsa/ subdirectory.  Go into alsa subdirectory, then
	ALSAKERNELDIR=../../sound ./gitcompile --with-debug=full --enable-dynamic-minors

Alternatively, you can pull the alsa-driver-built git into kernel tree
directly.  Then go to alsa subdirectory and run gitcompile.  In that
case, you can omit passing "ALSAKERNELDIR=..." argument.
