SPDX makes it a simpler diff.
I have audited the commit history of each file to ensure that they are
exclusively authored by IBM and thus we have the right to relicense.
The motivation behind this is twofold:
1) We want to enable experiments with coreboot, which is GPLv2 licensed
2) An upcoming firmware component wants to incorporate code from skiboot
and code from the Linux kernel, which is GPLv2 licensed.
I have gone through the IBM internal way of gaining approval for this.
The following files are not exclusively authored by IBM, so are *not*
included in this update (I will be seeking approval from contributors):

Ensure the (C) who and years are correct, based on git history.

This changes to build system to use thin archives rather than
incremental linking for built-in.o, similar to recent change to Linux.
built-in.o is renamed to built-in.a, and is created as a thin archive
with no index, for speed and size. All built-in.a are aggregated into
a skiboot.tmp.a which is a thin archive built with an index, making it
suitable or linking. This is input into the final link.
The advantags of build size and linker code placement flexibility are
not as great with skiboot as a bigger project like Linux, but it's a
conceptually better way to build, and is more compatible with link
time optimisation in toolchains which might be interesting for skiboot
particularly for size reductions.
Size of build tree before this patch is 34.4MB, afterwards 23.1MB.

Run a small wrapper around some unit tests with the QTEST makefile macro
(QTEST=Quiet TEST). Also, wrap boot tests in mambo and qemu to be quiet
by default.
Both ./test/run.sh and the modified mambo/qemu test runner scripts output
full stdout and stderr in the event of error.

Some versions of sparse (all?) don't support -std=gnu11 CFLAG, so filter
it out when calling sparse. Doesn't affect non-sparse build

As this is done on the Linux kernel, one can now run sparse using
C=1 on the command line. The variable CF can be used to tune the
sparse options.

Currently "make --silient" still produces a lot of output. This mutes it.
Plus alliteration is fun.

We use a double link technique, doing a first pass with a .o containing
a dummy symbol map, then re-linking with a new .o

It expands our % on the right hand of the built-in.o rule into
the directory name extracted from the prefix of the left hand
and that makes ld puke.
