Currently, the VFP selection for ARM is a little bit muddy:
- some CPUs definitely do not have a VFP or NEON,
- some CPUs definitely do have a VFP or NEON,
- some CPUs may have a VFP or NEON.
However, we currently conflate the availability of the VFP/NEON with the
possibility to use them. Even is the user chooses a floating point
strategy with a 'lower' solution (i.e. VFPv2 when a VFPv3 exists, or not
using NEON when the CPU has it), some packages are still using the
CPU-defined HW availaibility rather thean the usr's selection.
Furthermore, for CPU that may have a VFP/NEON, there is no way for the
user to actually specify that the HW is indeed available; the user can
only specify the floating point strategy. This means that some packages
or some package versions, like nodejs for example, can not be properly
selected on some CPU cores, like Cortex-A9 which only may have a VFP.
Like we have an option to enable an optional NEON unit, add a similar
option to enable an optional VFP unit.

Stating whether to use the NEON extensions when it is optional in the
CPU really is completing the definition of the CPU we've just selected.
Move the ENABLE_NEON option just after the choice of the CPU variant,
and before any "software" option (ABI/VFP).
This will make sense in a moment, when we introduce a similar option for
enabling an optional VFP unit.

This commit turns the single static option into a choice, which offers
various possibilities:
1. Build and use static libraries only;
2. Build both shared and static libraries, but use shared libraries;
3. Build and use shared libraries only.
On most platforms, (2) is currently the default, and kept as the
default in this commit. Of course, on certain platforms (Blackfin,
m68k), only option (1) will be available.
In addition to the introduction of the Config.in options, this commit
also:
* Removes the 'select BR2_STATIC_LIBS' from 'BR2_BINFMT_FLAT', since
with the use of a choice, we are guaranteed that BR2_STATIC_LIBS
will be selected when the binary format is BR2_BINFMT_FLAT, since
BR2_STATIC_LIBS will be the only possible solution in the choice.
* Changes package/Makefile.in to use the proper

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.

The fuzzy generic x86 variant doesn't make much sense in the context of
Buildroot, and the recent change to use -march instead of -mtune broke it.
From the GCC manual:
https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/i386-and-x86-64-Options.html#i386-and-x86-64-Options:
-mtune=cpu-type
Tune to cpu-type everything applicable about the generated code,
except for the ABI and the set of available instructions. While
picking a specific cpu-type schedules things appropriately for that
particular chip, the compiler does not generate any code that cannot
run on the default machine type unless you use a -march=cpu-type
option. For example, if GCC is configured for i686-pc-linux-gnu then
-mtune=pentium4 generates code that is tuned for Pentium 4 but still
runs on i686 machines.
The choices for cpu-type are the same as for -march. In addition,
-mtune supports 2 extra choices for cpu-type:
‘generic’
Produce code optimized for the most common IA32/AMD64/EM64T
processors. If you know the CPU on which your code will run,
then you should use the corresponding -mtune or -march option
instead of -mtune=generic. But, if you do not know exactly what
CPU users of your application will have, then you should use
this option.
As new processors are deployed in the marketplace, the behavior
of this option will change. Therefore, if you upgrade to a newer
version of GCC, code generation controlled by this option will
change to reflect the processors that are most common at the
time that version of GCC is released.
There is no -march=generic option because -march indicates the
instruction set the compiler can use, and there is no generic
instruction set applicable to all processors. In contrast,
-mtune indicates the processor (or, in this case, collection of
processors) for which the code is optimized.

Set the instruction scheduling parameters for machine type
CPU_TYPE, but do not set the architecture type, register usage, or
choice of mnemonics, as '-mcpu=CPU_TYPE' would. The same values
for CPU_TYPE are used for '-mtune' as for '-mcpu'. If both are
specified, the code generated will use the architecture, registers,
and mnemonics set by '-mcpu', but the scheduling parameters set by
'-mtune'.
In the case of Buildroot where we only target a specific system, using

In commit 88cf3bb917
("arch/Config.in.arm: Use armv6k for arm1136jf-s rev1"), Benoît
Thébaudeau added separate options for the revision 0 and revision 1 of
the ARM1136JF-S processor, so that different -march values could be
used (armv6j for revision 0, armv6k for revision 1).
However, this is preventing the removal of the BR2_GCC_TARGET_ARCH
option, which we need to do to give only the CPU type to gcc, and let
it decide the architecture variant that matches. This is because this
story of revision 0 vs. revision 1 is the only case where -mcpu
doesn't fully define the CPU.
Moreover, a quick test with gcc shows that -march=armv6j
-mcpu=arm1136jf-s is accepted, while -march=armv6k -mcpu=arm1136jf-s
makes gcc complain: " warning: switch -mcpu=arm1136jf-s conflicts with
-march=armv6k switch".
In addition, gcc 5 will apparently no longer allow to pass all of
--with-arch, --with-cpu and --with-tune, so we will anyway have to
rely only on one of them.
As a consequence, this commit basically reverts
88cf3bb917 and provides only one option
for ARM1136JF-S. If the two revisions are really different, then they
should be supported in upstream gcc with different -mcpu values.
Note that the removal of the two options should not break existing
full .config, since the hidden option BR2_arm1136jf_s becomes again a
visible option to select the CPU.
