I am afraid, but those changes do not belong to the universal source package. You may create an androidcompile script (something like gitcompile) with some reasonable defaults for configure / autoconf / automake.
If something is missing in the autoconf/automake files - just add it there.
Thank you for review the patches.
Android doesn't use autoconf/automake. Android uses non-recursive build system. The main makefile will include all Android.mk found in the source tree and make all necessary targets to build the final image.
This patch just adds two files to the android/ subfolder which intends to work with Android build system. We just pull the alsa-lib (and alsa-utils, will send later) code to Android source tree and build them. It won't affect others. I hope to upstream them so other people don't need to re-invent the wheel.
Several upstream projects we use have accepted such patches. For examples:
efivar: https://github.com/rhboot/efivar/pull/125 libva: https://github.com/intel/libva/pull/37 vaapi: https://github.com/intel/intel-vaapi-driver/pull/446 exfat: https://github.com/relan/exfat/pull/53 libdrm: https://cgit.freedesktop.org/mesa/drm/tree/Android.mk mesa: https://cgit.freedesktop.org/mesa/mesa/tree/Android.mk
In particular, libdrm / mesa have added Android makefiles and maintained them for years. I hope you can consider to accept it.
