readelf is not a bootstrap tool and so cannot be relied upon to exist.
On macOS there is no system readelf, and even on Linux or FreeBSD where
it does exist, BUILD_WITH_STRICT_TMPPATH builds won't be able to use it.
Instead of making it a bootstrap tool, just use nm as that suffices and
already is a bootstrap tool.

sys/tools: Add a tool for generating arm and arm64 kernel images.2020-12-30T12:22:04ZMichal Melounstrejda@users.noreply.github.com2020-12-29T13:49:41Zurn:sha1:59f46e34cf640a057e7445960a807004ce4de9ff
This tool can generate kernel images without changing the offsets in
the final executable. It replaces the ELF header by properly sized zeroed
block then emits a relative jump to _start(for 'v7jump' or 'v8jump' option)
or the booti header (for 'v8booti' option) to the beginning of the converted file.
