Usage: $PROGNAME [options] [<path-to-toolchain-sources>]
This script is used to rebuild a custom Linux host toolchain that targets
GLibc $GLIBC_VERSION or higher. The machine code generated by this toolchain
will run properly on Ubuntu $UBUNTU_RELEASE or higher.
If you're running on a 32-bit system, it will generate a 32-bit toolchain.
If you're running on a 64-bit system, it will generate a 64-bit toolchain
unless you use the --32-bits option.
You can provide the path to a local copy of the toolchain sources repository
as a first parameter. If you don't, the sources will be downloaded and
extracted automatically into your work directory.
Note that this script will download various binary packages from Ubuntu
servers in order to prepare a compatible "sysroot".
By default, it generates a package archive ($TOOLCHAIN_ARCHIVE) but you can,
as an alternative, ask for direct installation with --prefix=<path>
Use the bootstrap option to re-generate the toolchain with itself. This is
useful if you want to ensure that the generated compiler binaries will work
properly on Ubuntu 8.04 or higher. By default, they will only run on systems
that match your build system's C library ABI, or higher.
