Overview
This directory contains files that make it possible for Linux distributions to build Chromium using system toolchain.
For more info on established way such builds are configured, please read the following:
Why do distros want CFLAGS, LDFLAGS, etc? Please read the following for some examples. This is not an exhaustive list.

Usage
Add the following to GN args:
custom_toolchain="//build/toolchain/linux/unbundle:default"
host_toolchain="//build/toolchain/linux/unbundle:default"
See more docs on GN.
To cross-compile (not fully tested), add the following:
host_toolchain="//build/toolchain/linux/unbundle:host"
v8_snapshot_toolchain="//build/toolchain/linux/unbundle:host"
Note: when cross-compiling for a 32-bit target, a matching 32-bit toolchain may be needed.
