workaround for bootstrap_sdk on an Ubuntu host where /dev/shm is a
symlink to /run/shm. Since we mount the hosts /dev (for losetup) this
interferes with building python 2.7. The workaround is to disable the
/dev/shm during python builds. A longer term fix would be to not mount
the hosts /dev. Thanks for marineam for suggesting the fix on IRC.
Instead of patching portage to support the `disabled` flag now we just
patch it to leave the `[gentoo]` section out of the default repos.conf.

This variable was semi-deprecated ages ago so `version.txt` could follow
a similar variable naming pattern to `os-release`. Finally drop usage of
it here in favor of `$COREOS_VERSION`.
Now that ccache is turned on by default in the profile portage complains
a lot if ccache isn't actually installed, sleeping 5 seconds for each
error message. Since pkgcache is in use ccache isn't going to make that
much of a difference but getting rid of those 5 second sleeps will. :)
This is required for the eventual removal of `$PORTDIR` and
`$PORTDIR_OVERLAY` and ensures toolchain rebuilds/updates with
`./build_packages --nousepkg` don't erroniously try to use ebuilds from
`/usr/portage` inside of the SDK.
In order to fix up the build_toolchains script the crossdev overlay
needs to be setup properly, previously only setup_board did it.
Overall silences a lot of warnings and fixes an issue with crossdev:
/usr/bin/emerge-wrapper: line 48: /eclass/toolchain-funcs.eclass: No such file or directory
/usr/bin/emerge-wrapper: line 49: tc-arch: command not found
Disable ccache as it is causing issues in other builds so disable it
everywhere to be safe. Disable the autoresume feature because our build
process doesn't actually make use of it.
Adding the update step appears to break permissions on the distfiles
directory. Ensure the portage user is correct and set the permissions on
directories it needs to write to in advance.
When bootstrapping a SDK we need to update GCC dependencies to ensure
the GCC built for stage1 is linked against the same library versions as
those that are included in the stage1. Without this updating the mpc
library just results in a broken stage1.
This doesn't make things go faster and I am suspicious that it makes
things worse. For example /etc/xml/catalog winds up empty from time to
time and I wonder if this locking is related to that.
Right now there is some funky logic to either use a previous build as a
seed or the current SDK tarball if it happens to have been downloaded.
This is a bit confusing and doesn't work reliably since it is reasonable
for there to be neither a previous build or the current SDK available if
the SDK chroot was created some time ago. Fix this by using the new SDK
library and always use the latest SDK, downloading it if needed.
A number of places refer to these paths and that number is going to
grow. Since the standard pattern is to use environment variables for
commonly used paths it is time to add ones for these:
REPO_CACHE_DIR
REPO_MANIFESTS_DIR
Use 2*CPUs for the target load average but add load average throttling
to emerge in addition to make. Also work around how catalyst sets
FEATURES so we can disable extra locking for hopefully faster builds.
