This is especially useful for cross compiling using SDK outputs from build systems like yocto, which often have custom toolchain prefixes. Signed-off-by: Robert Beckett <bob.beckett@collabora.com>

A couple of changes used to build via a custom toolchain and sysroot.
With these changes, I was able to build for arm 32bit Linux with args.gn like:
target_os = "linux" target_cpu = "arm" is_debug = false is_clang = false target_sysroot = "/opt/PROJECT-sdk/sysroots/armv7ahf-neon-PROJECT-linux-gnueabi" target_triplet = "arm-PROJECT-linux-gnueabi" target_extra_cflags = "-mfloat-abi=hard"
