Similar to toolchains, we now offer a way for br2-external trees to
provide their libjpeg implementation, which gets included in the jpeg
choice.

>From the 1.5-b1 release notes:
Added ARM 64-bit (ARMv8) NEON SIMD implementations of the commonly-used
compression algorithms (including the slow integer forward DCT and h2v2 &
h2v1 downsampling algorithms, which are not accelerated in the 32-bit NEON
implementation.) This speeds up the compression of full-color JPEGs by about
75% on average on a Cavium ThunderX processor and by about 2-2.5x on average
on Cortex-A53 and Cortex-A57 cores.
Add it unconditionally for all aarch64 cores, as neon support is required
for all "standard" ARMv8 implementations. If an ARMv8 implementation w/o
NEON ever shows up, then we will need to add a BR2_AARCH64_CPU_HAS_NEON and
handle it like ARM.

>From the 1.5-b1 release notes:
Added full SIMD acceleration for PowerPC platforms using AltiVec VMX
(128-bit SIMD) instructions. Although the performance of libjpeg-turbo on
PowerPC was already good, due to the increased number of registers available
to the compiler vs. x86, it was still possible to speed up compression by
about 3-4x and decompression by about 2-2.5x (relative to libjpeg v6b)
through the use of AltiVec instructions.

In preperation for adding more architectures to the jpeg-turbo simd
handling, introduce a hidden BR2_PACKAGE_JPEG_SIMDS_SUPPORT symbol and use
that to enable simd support and default to jpeg-turbo, instead of open
coding it in both places.
While we are at it, reword the help text to be more useful.

Currently, the virtual package jpeg is a special virtual package,
as it offers a choice for its implementation, rather than letting the
user enable them manually.
In so doing, it defines its _HAS option as a 'def_bool y' rather than
letting each implementation 'select' it.
Since we are going to generate a list of virtual packages and their
providers, this defeats the heuristic used to find providers.
Coming with an alternate heuristic that also matches the jpeg
package is quite complex, so better and easier to make it look more
like any other virtual package.

Since this package is implemented via a choice rather than the usual
separate-package providers, we only need BR2_PACKAGE_HAS_JPEG to be
always defined when the 'jpeg' package is selected.

jpeg is a virtual package, but since it is listed in the dependencies
of other packages, it should obey to all the normal make rules for
packages. Notably, the jpeg-show-depends target is mandatory for the
graph-depends script to work.
Instead to implement such a make target manually, make jpeg a normal
generic-package, except that it doesn't have any source.

Introduce a virtual 'jpeg' package, which pulls in either libjpeg or
jpeg-turbo depending on a choice selection.
Rename jpeg package to libjpeg so we can reuse 'jpeg' for the virtual
package, making the change transparent to existing users and all the
packages using libjpeg.

they should be configured with --prefix=/usr and we then need to use
make DESTDIR=$(STAGING_DIR) install to get things installed into the
staging directory. The current situation for many packages, which use
--prefix=$(STAGING_DIR) results in the staging_dir paths getting compiled
into the binary itself.
This also adds in a pile of libtool fixups. Between broken pkgconfig,
broken libtool handling, and broken --prefix settings, its a wonder
things have worked as well as they have up till now.
