The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

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.

We've supported this for a long time, plus most u-boot setups quietly expect
it. Otherwise they fail with different levels of memory overwrites.

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.
