tools build: Fix feature test for rust compiler

Currently a dummy rust code is compiled to detect if the rust feature
could be enabled. It turns out that in this case rust emits a dependency
file without any external references:

/perf/feature/test-rust.d: test-rust.rs

/perf/feature/test-rust.bin: test-rust.rs

test-rust.rs:

This can lead to a situation, when rustc was removed after a successful build,
but the build process still thinks it's there and the feature is enabled on
subsequent runs.

Instead simply check the compiler presence to detect the feature, as
suggested by Arnaldo.

This way no actual test-rust.bin will be created, meaning the feature
check will not be cached and always performed. That's exactly what we
want, and the overhead of doing this every time is minimal.

Tested with multiple rounds of install/remove of the rust package.

spi: Octal DTR support

This series adds support for 8D-8D-8D in SPI NAND, which can already be
leveraged without any SPI changes as controllers already have this
support for some SPI NOR devices.

Among the few spi-mem patches, they are needed for building the SPI NAND
changes (especially the ODTR introduction at the end) and therefore an
immutable tag will be needed for merging in the MTD tree (unless all the
series goes through MTD directly ofc).

Merge series from André Draszik <andre.draszik@linaro.org>:

With these attached patches it becomes possible again to support
hardware designs with multiple PMICs where individual rails of each act
as required supplies for rails of the other (due to the latter being
e.g. always-on), and vice-versa.

Google Pixel 6 and 6 Pro (oriole and raven) are examples of such
designs.

Rather than returning -EPORBE_DEFER in regulator_register() when
set_machine_constraints() fails with -EPROBE_DEFER (due to missing
required supplies), we still allow rail registration and try to
reresolve supplies each time a new rail gets registered.

This is implemented using a bus (regulator bus), which allows the core
to reresolve supplies for regulators that still need them whenever new
regulators (i.e. devices) are added.

Using a bus also solves existing problems around late resolution of
supplies as mentioned in the commit message introducing that bus.

The series starts with a few bug fixes and the last two commits
implement the changes mentioned above, but do depend on the bug fixes.
