Switch from bz2 to gz tarball output. bz2 is slowly being replaced by lz variants, but gzip isn't going anywhere. (It retains a niche as a streaming protocol, it's the 80/20 solution optimizing for speed, low memory requirements, and simple compressor implementation.)

# Build a compiler for a given target, using one or more existing simple
# cross compilers.

# This can be used to build a native compiler for an aribitrary target, or to
# build a more portable and capable cross compiler for an arbitrary host.

# The new compiler is built --with-shared, with thread support, has uClibc++
# installed, and is linked against musl (see BUILD_STATIC in config).
