# Create Alpine 3.15 (musl 1.2.2) container suitable for cross-compiling musl-based Linux ARM64v8-A binaries

# Musl defaults to static libs but we need them to be dynamic for host toolchain.
# The toolchain will produce static libs by default.
# We also need to add the directory containing libc.a to the library search path.
