32bit compatibility is the default for now with 64bit gnumach, until 64bit userland is ready. Here we however want native 64bit userland anyway.

"""Build many configurations of glibc.
|
|
|
|
This script takes as arguments a directory name (containing a src
|
|
subdirectory with sources of the relevant toolchain components) and a
|
|
description of what to do: 'checkout', to check out sources into that
|
|
directory, 'bot-cycle', to run a series of checkout and build steps,
|
|
'bot', to run 'bot-cycle' repeatedly, 'host-libraries', to build
|
|
libraries required by the toolchain, 'compilers', to build
|
|
cross-compilers for various configurations, or 'glibcs', to build
|
|
glibc for various configurations and run the compilation parts of the
|
|
testsuite. Subsequent arguments name the versions of components to
|
|
check out (<component>-<version), for 'checkout', or, for actions
|
|
other than 'checkout' and 'bot-cycle', name configurations for which
|
|
compilers or glibc are to be built.
|
|
|
|
The 'list-compilers' command prints the name of each available
|
|
compiler configuration, without building anything. The 'list-glibcs'
|
|
command prints the name of each glibc compiler configuration, followed
|
|
by the space, followed by the name of the compiler configuration used
|
|
for building this glibc variant.
