This brings our default build config more in line with what is
necessary for some platforms anyway: using the system-installed
toolchain and sysroot to build everything.
We will no longer fetch source or binaries for any specific build
tools, such as libc++, clang, gold, binutils, or valgrind.
The main part of this change is the changing of default gyp settings
in gyp_packager.py. For this, a bug in gyp_packager.py had to be
fixed, in which similar GYP_DEFINE key names (such as clang and
host_clang) would conflict, causing some defaults not to be installed
properly.
In order to enable clang=0 by default, some changes had to be made in
common.gypi:
- compiler macros added to fix a compatibility issue between
Chromium's base/mac/ folder and the actual OSX SDK
- replaced clang_warning_flags variables with standard cflags
settings, plus xcode_settings for OSX
- turned off warnings-as-errors for non-shaka code, rather than
allow-listing specific warning types, since we can't actually fix
those warnings on any platform
- disabled two specific warnings in shaka code, both of which are
caused by headers from our non-shaka dependencies
Also, one warning (missing "override" keyword) has been fixed in
vod_media_info_dump_muxer_listener.h.
Although these changes were done to make building simpler on a wider
array of platforms (arm64, for example), it seems to make the build a
bit faster, too. For me, at least, on my main Linux workstation:
- "gclient sync" now runs 20-30% faster
- "ninja -C out/Release" now runs 5-13% faster
The following environment variables are no longer required:
- DEPOT_TOOLS_WIN_TOOLCHAIN
- MACOSX_DEPLOYMENT_TARGET
Documentation, Dockerfiles, and GitHub Actions workflows have been
updated to reflect this.
The following GYP_DEFINES are no longer required for anyone:
- clang=0
- host_clang=0
- clang_xcode=1
- use_allocator=none
- use_experimental_allocator_shim=0
Documentation, Dockerfiles, and GitHub Actions workflows have been
updated to reflect this.
The following repos are no longer dependencies in gclient:
- binutils
- clang
- gold
- libc++
- libc++abi
- valgrind
The following gclient hooks have been removed:
- clang
- mac_toolchain
- sysroot

Alpine does not support python3 yet, but depot_tools enabled python3
by default recently.
Disable python3 for now.
Fixes#763.

Keep bundled binutil scripts but not downloading actual binaries by default.
Automatic downloading of binutils has been causing problems for some users:
see #164, #412, #440.
Using bundled binutils helps reduce linking time, but packager codebase is
relatively small, so the gain is not significant.
Local testing shows that the full build time increases from 1m42s to 1m50s, i.e.
an increase of about 8s, or ~8%.
User can still enable the usage of bundled binutils by running
'python src/packager/third_party/binutils/download.py' and set
'linux_use_bundled_binutils' and 'linux_use_bundled_gold' to 1 in GYP_DEFINES.

- Also fixed compilations in Alpine Linux and other flavors of Linux.
- Added container versions in docker files to always use a verified
version.
Closes#164.
