package/newlib-bare-metal: add multiple tuple support

Browse Source 
Add support to gcc-bare-metal to support multiple architecture tuples
with the BR2_TOOLCHAIN_BARE_METAL_BUILDROOT_ARCH string.

To do this, custom configure, build and install commands are needed, so that
each step goes through a loop of the architecture tuples in the list.

To keep consistency with autotools, all the relevant target configurations
have been copied into the NEWLIB_BARE_METAL_CONF_OPTS while removing any
configurations that do not apply to newlib.

Also, the following configs were not taken because newlib is being built for
each of the bare-metal targets and not the main target of Buildroot.

$$(TARGET_CONFIGURE_OPTS)
$$(TARGET_CONFIGURE_ARGS)
--target=$$(GNU_TARGET_NAME)
--host=$$(GNU_TARGET_NAME)
