- prompt "Link Time Optimization (LTO)"
- default LTO_NONE
- ---help---
- This option enables Link Time Optimization (LTO), which allows the
- compiler to optimize binaries globally.
-
- If unsure, select LTO_NONE. Note that LTO is very resource-intensive
- so it's disabled by default.

-config LTO_NONE
- bool "None"
- ---help---
- Build the kernel normally, without Link Time Optimization (LTO).

-config LTO_FULL
- bool "GNU Full LTO (EXPERIMENTAL)"
- depends on ARCH_TOOLCHAIN_GNU
- ---help---
- Link time optimization is implemented as a GCC front end for a bytecode
- bytecode representation of GIMPLE that is emitted in special sections
- of .o files. Currently, LTO support is enabled in most ELF-based systems,
- as well as darwin, cygwin and mingw systems.

-config LTO_THIN
- bool "Clang ThinLTO (EXPERIMENTAL)"
- depends on ARCH_TOOLCHAIN_CLANG
- ---help---
- This option enables Clang's ThinLTO, which allows for parallel
- optimization and faster incremental compiles compared to the
- CONFIG_LTO_FULL option. More information can be found
- from Clang's documentation:
-
- https://clang.llvm.org/docs/ThinLTO.html

- If unsure, say Y.

Review Comment:
Just separates the toolchain related configuration into Kconfig.toolchain, new toolchain support can be added to this file
