The armv8.1a generation is a cumulative extension to armv8a. It adds new
extensions, and makes some previously optional ones now mandatory.
Since gcc correctly enables the appropriate extensions based on the core
name, we don't really need to introduce a separate config for armv8.1a,
and we can piggyback on armv8a.
All those new cores are aarch64 only (gcc fails to build in arm mode).

Reorder the choice by architecture generation, starting with armv4,
ending with armv8.
Add a comment before each generation, just for ease of use. Add a

Finally, order cores alphabetically inside the same generation (except

Currently, the possibility to choose the floating point mode (32, xx or
64) is conditional on having a sufficiently recent gcc version.
Which means that the architecture selection depends on the gcc version.
But that's opposite to what we've always done in Buildroot: the software
versions are conditional to the architecture options. There is nothing
we can do about the hardware: it is there, we can't change it, while we
can restrict ourselves to using software that is working on said
hardware.
Thus, we inverse the logic, to move the condition onto the software
side: whenever mfpxx is selected, we restrict the toolchain selection to
at least a gcc-5.
And now, the blind BR2_TOOLCHAIN_HAS_MFPXX_OPTION symbol is no longer
needed, so we get rid of it.

Some CPU variants require that a recent-enough gcc be selected. For
example, ARM's cortex-a35 requires gcc-5, while cortex-a73 requires
gcc-7. Same goes for other architectures, of course.
Currently, we hard-code every such conditions in the gcc version choice,
as well as in the individual external toolchains.
However, as we add even more CPU variants, the conditions are getting
more and more complex to write and maintain.
Introduce new symbols, that architectures can select if they have a
specific requirement on the gcc version. gcc and external toolchains
can then properly depend on those symbols.
The burden of maintaining the requirements on the gcc version now falls
down to the architeture, instead of being split up in gcc and all the
external toolchains.
As the oldest gcc version to handle, we can either choose gcc-4.9, as
the oldest version we support in our internal toolchain, or choose
gcc-4.8, as the oldest external toolchain we support (except for the
custom ones, but they'll be handled specifically in upcoming changes).
We choose to go back up to gcc-4.8.

Those cores are not supported in upstream gcc, not even in master.
The only toolchain that supported those core was the 2014R1 ADI
rebuilt toolchain, but we removed it in 311bc13 (toolchain: kill
ADI Blackfin toolchain) because there was too many issues with it.
ADI has not released any newer toolchain since then.
There is little hope for those cores now, so remove them.
Support for those cores has been useless and unusable for a while
without nobody noticing, therefore we intentionally skip adding
Config.in.legacy. This would require keeping code in

This poses a maintainance burden, as the knowledge about what gcc
version supports what architecture is split across many places: the

currently, specifying a custom Xtrensa core is done with two variables:
- the core name
- the directory containing the overlay tarball
However, the core name only serves to construct the tarball name, and is
not used whatsoever to configure any of the toolchain components
(binutils, gcc or gdb), except through the files that are overlayed in
their respective source trees.
This has two main drawbacks:
- the overlay file must be named after the core,
- the tarball can not be compressed.
Furthermore, it also makes it extremely complex to implement a download
of that tarball.
So, those two variables can be squeezed into a single variable, that is
the complete path of the overlay tarball.
Update the qemu-xtensa defconfig accordingly.
Note: we do not add a legacy entry for BR2_XTENSA_CORE_NAME, since it
was previously a blind option in the last release, and there's been no
release since we removed BR2_XTENSA_CUSTOM_NAME. So, we just update the
