v1.25.0

This update pulls in Buildroot 2023.08.2. This is a major Buildroot update from
v1.24.1 with possibly the biggest change for Nerves users being the update from
OpenSSL 1.1.1 to OpenSSL 3.

Nerves systems need the following updates:

1. Buildroot 2023.08 updated the default GCC version to GCC 13. Since Nerves
   systems and toolchains are mostly on GCC 12 which was the default, the
   nerves_defconfig will need to be updated to select GCC 12. Add
   BR2_TOOLCHAIN_EXTERNAL_GCC_12=y to nerves_defconfig.
2. Buildroot's toolchain feature detection is better. OpenMP and Fortan support
   are autodetect and checked against toolchain features specified in
   nerves_defconfig. To fix the warnings, add
   BR2_TOOLCHAIN_EXTERNAL_FORTRAN=y and BR2_TOOLCHAIN_EXTERNAL_OPENMP=y to
   nerves_defconfig.
3. If using a RISC-V processor, you may need to enable the atomic instructions
   in the target selection. If you get build errors with Erlang concerning
   atomics, this is likely the issue.
