Thanks for working on this!

It would be good to add the upstream status of this patch here. Was it
sent upstream? If so, a link?

We like to have a blank line followed by the URL of the project
homepage, at the end of the Config.in help text.

We also need a hash for the license file.

There is no dependency on host-rustc ? How can the rust compiler be
available prior to building this package then ?

Is PREFIX= needed at build time ?

I think we will prefer to not have BUILD_OPTS/INSTALL_OPTS but instead:

UUTILS_COREUTILS_MAKE_OPTS = \
	PROFILE=release \
	MULTICALL=y

define UUTILS_COREUTILS_BUILD_CMDS
	$(TARGET_MAKE_ENV) $(TARGET_CONFIGURE_OPTS) $(MAKE) \
		$(UUTILS_COREUTILS_MAKE_OPTS) -C $(@D)
endef

define UUTILS_COREUTILS_INSTALL_TARGET_CMDS
	$(TARGET_MAKE_ENV) $(MAKE) \
		$(UUTILS_COREUTILS_MAKE_OPTS) -C $(@D) \
		PREFIX=$(TARGET_DIR) install
endef

(assuming PREFIX= is only needed at install time)

It does the same, but the above suggestion is a bit more idiomatic in
Buildroot.

Best regards,

Thomas
