+ Enable or disable the ``--enable-newlib-reent-thread-local`` Newlib
+ configuration option. This option is enabled by default on the aarch64, arm,
+ nios2, powerpc, riscv, and sparc targets. If this option is enabled, then
+ each member of the Newlib struct _reent is replaced by a dedicated
+ thread-local object. The thread-local objects are defined in translation

The RSB provides build sets for some BSPs. These build sets will build:
- Compiler, linker, debugger and RTEMS Tools.
