[bug #61240] gcc 10.2.1-6 cannot compile gcc 10.2.0; related: unwind, iconv

[Boud Roukema]

Follow-up Comment #8, bug #61240 (project reproduce):

Upgrading both the host system gcc _and_ the Maneage gcc was necessary.

Commit aacd9b5 [1] removes the previous hack, removes '--disable-multiarch',
upgrades gcc and coreutils, and Maneage should be fully reproducible from
scratch through to the verification sums on the pinephone, apart from some
minor caveats [2][3], which should probably go into a README.aarch64 file. So
I propose aacd9b5 for merging into Maneage (the urls can be recommented once
there are zenodo/akhlaghi.org copies in place). Once that's merged, I'm fine
for closing this bug.

[2] Vampires may be a problem on the pinephone/aarch64. A "vampire" is defined
here as a job that is in the "R" (running) state, using nearly 95-100% of a
cpu, for an extremely long time (hours), without producing any output to its
log file, and is immune to being killed by the user or root with 'kill -9'. A
reboot and relaunch of the './project configure --existing-conf' command is
the only solution currently known (to me) for vampires. These are known to
have occurred with linux-image-5.13-sunxi64 .

[3] Adding 3 Gb of swap space (man swapon, man mkswap, man dd) on the eMMC may
help to reduce the chance of having errors due to the lack of RAM.
