Build Skia for a bare-bones embedded Linux system. Motivation: I have downloaded a barebones Linux system built for 64-bit ARM from linaro.org and a ARMv8 Foundation Model from arm.com to run it on. This will let us build and test Skia on ARM64 before we aquire hardware to allow that. This CL introduces the changes to the build files necessary to build Skia on a barebones embedded Linux system. I tested it with the aarch64 GCC compiler provided by linaro.org. Changes: Add a "barelinux" target_os for the DEPS file. Add an optional git download of zlib. Changes to gyp files: these changes abstract out libpng, libz, and giflib so that images.gyp doesn't know whether they are static or dynamically linked. I also add the variables skia_giflib_static, skia_libpng_static, skia_zlib_static, and skia_freetype_static, all of which default to false but when set to true will override the behavior of the giflib, libpng, zlib, and freetype build targets to require them to build statically. Also, the skia_no_fontconfig variable turns off use of the fontconfig service. Scripts in platform_tools/barelinux/bin: arm64_download - this script downloads the Linaro's ARMv8 Aarch64 toolchain and minimal embedded Linux system as well as ARM's foundation model. The required files are mirrored on Google Cloud. The script then starts a emulated Arm64 Linux system in the background. After the boot is complete, you can SSH into the system at port 8022 via user@localhost. The SSH key will be downloaded into the working directery as well. download_deps - Uses gclient to download Skia's dependencies for a bare Linux system (the normal dependecies plus giflib, libpng, and zlib.) barelinux_make - this script builds a version of skia that does not depend on external libraries, perfect for putting in an embedded system running Linux. Assumes you have run download_deps first. To test: To build a barelinux target, use the barelinux_make script. To build for a armv8 system: skia_arch_type=arm arm_neon=0 armv7=1 armv8=1 arm_thumb=0 skia_arch_width=64 and set the CC and CXX variables to point at the cross-compiler downloaded by arm64_download.
