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 that you have already run the download_deps script.

Usage:
  $0 \\
    [-o SKIA_OUT_DIR] [-c CC_EXE] [-x CXX_EXE] \\
    [-t Debug | Release | Coverage | Release_Developer] \\
    [GYP_DEFINES...]

Example use:
  $0 \\
    -o ~/build/skia/arg64gcc \\
    -c ~/local/arm64/bin/aarch64-linux-gnu-gcc \\
    -x ~/local/arm64/bin/aarch64-linux-gnu-g++ \\
    skia_gpu=0 skia_arch_type=arm skia_arch_width=64 \\
    armv7=1 armv8=1 arm_neon=0 arm_thumb=0
