Sometimes the default GCC and newlib libraries built for a given
architecture tuple are not based on the desired ABI. Since ABI definitions are
different between architectures, the simplest solution is to allow users to
build bare-metal toolchains with --enable-multilib. This way, the libraries
for every available ABI will be built and users will be able to select the
desired library for their user applications.
This patch adds the option BR2_TOOLCHAIN_BARE_METAL_BUILDROOT_MULTILIB to give
users the choice to enable multilib, if desired.
Please note that when using a string of architecture tuples, this option will
apply to all architectures in the string, so it can significantly increase
build time.
