with structuredAttrs lists will be bash arrays which cannot be exported
which will be a issue with some patches and some wrappers like cc-wrapper
this makes it clearer that NIX_CFLAGS_COMPILE must be a string as lists
in env cause a eval failure
/proc/uptime support can't be detected automatically when cross-compiling, so
it is disabled by default. This causes extremely large uptime values (e.g.
19167 days) on systems without RTCs because the boot time is set to the
epoch.
I suspect this issue is caused by the very old version of diffutils we
have in the aarch64+musl bootstrap tools, so hopefully we can
re-enable the tests once we have newer bootstrap tools.
Until a recent patch in coreutils, gnus uname -p returned a different
arch on apple silicon macs, compared to the uname shipped with macos.
This causes config.guess to produce incorrect build system triplets
for various projects on these systems when in a nix-shell.[23][42]
As coreutils only releases every few months/years and no release is
planned at the moment, I'm introducing the patch here. We can drop it
once the next coreutils version is released.
I made a tiny adjustment to the patch from [23]. I removed the usage
of MAYBE_UNUSED, which currently only compiles against HEAD.

The arm patch tries to modify files that are nowhere to be found in the
entire source tree. The cygwin patch also doesn't work so good anymore:

Tested on 16-core machine with 10 rebuilds:
$ nix build -f. coreutils --repeat 10
No failures. Original failure is probably fixed upstream
with a69e54cfdf7 ("maint: fix dependency of man/arch.1".)
