Complete build log

When attempting to emerge dev-lang/rust-1.62.1 under the
default/linux/arm64/17.0/big-endian profile, the build fails with
the following message:

OSError: [Errno 8] Exec format error: '/var/tmp/portage/dev-lang/rust-1.62.1/work/rust-stage0/bin/cargo'

This is because the cargo binary it's trying to run is compiled for
little endian:

 # file '/var/tmp/portage/dev-lang/rust-1.62.1/work/rust-stage0/bin/cargo'
/var/tmp/portage/dev-lang/rust-1.62.1/work/rust-stage0/bin/cargo: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 4.2.6, with debug_info, not stripped

Yeah profile should add wd40 feature, there’s no upstream bootstrap tarball for arm64_be, and no plans to provide one like we do for sparc.
