# This file defines //build/toolchain/musl-host-gcc:musl_host_cc_suite.
#
# This is a C++ toolchain that uses GCC from the host at hardcoded paths, with
# a pre-built sysroot tarball that targets Metropolis nodes with musl and Linux
# headers.  It's a superset of //build/toolchain:host_cc_suite.
# For more information, see README.md.
