Back many years ago, we developed an Eclipse plugin that simplified
the usage of Buildroot toolchains. Enabling the BR2_ECLIPSE_REGISTER=y
was registering the Buildroot toolchain into a special file in your
HOME folder that the Eclipse plugin would recognize to allow to
directly use the Buildroot cross-compiler.
This Eclipse plugin has not been maintained for years. The last commit
in the repository dates back from September 2017. Since then Eclipse
has moved on, and the plugin is no longer compatible with current
versions of Eclipse.
Also, Eclipse is probably no longer that widely used in the embedded
Linux space, as other more modern IDEs have become more popular.
All in all, it's time to say good bye to this Eclipse integration.

While introducing gcc bug 99410 I've named BR2_TOOLCHAIN_HAS_GCC_BUG_ to
99140 that is wrong. So let's fix this by changing bug option to
BR2_TOOLCHAIN_HAS_GCC_BUG_99410.

The MMU option is currently located in the "Toolchain" menu, but it
doesn't make sense as it's really architecture related. In addition,
the selection of MMU has an impact on the choice of binary format
available, which is visible in the architecture menu.
Therefore, this commit moves the MMU option into the architecture
menu.
However, if we simply move it in arch/Config.in, it means that we
would have the following order of options:
Target architecture
Target architecture variant
ABI
MMU
Binary format
But really, the MMU option should be right below the Target
architecture variant, and the available ABIs derived from that.
The variant and ABI are arch-specfic, and defined in the per-arch
Config.in fragments; a Kconfig option can have only one prompt defined,
even under conditions, and appears at the place in the menu where its
prompt was defined. So, there is no (easy) possibility to have a
generic option appear where we want it.
Since in fact only 2 architectures show a visible prompt for the MMU
option (RISC-V and Xtensa), we move this option in
arch/Config.in.riscv and arch/Config.in.xtensa.
Some walkthrough the commit:
- BR2_ARCH_HAS_MMU_MANDATORY and BR2_ARCH_HAS_MMU_OPTIONAL are
removed as they are no longer needed
- BR2_USE_MMU becomes a hidden boolean
- All the places where we used to select BR2_ARCH_HAS_MMU_MANDATORY
now select BR2_USE_MMU directly.
- Introduce BR2_RISCV_USE_MMU and BR2_XTENSA_USE_MMU.
- All defconfigs that used "# BR2_USE_MMU is not set" are switched to
using the new option.
All in all, this simplifies things quite a bit, and allows to have a
good option ordering in the Target architecture menu.
This commit might raise a concern in terms of backward compatibility
with existing configurations. The only configurations that will be
broken by this change are RISC-V noMMU (which was very recently
introduced) and Xtensa noMMU (which we can probably agree is not such
a widely popular configuration).

for which no workaround exists. This causes build breakage in a number
of packages, so this commit introduces a

all binutils versions are affected, this option is true whenever the
