Can you assess the impact on the packages we currently have in
Buildroot ? I.e, which packages can only work with locale support?

If we remove BR2_TOOLCHAIN_BUILDROOT_LOCALE, then there's a lot of
possible further cleanup: BR2_ENABLE_LOCALE should be removed, all
packages doing select BR2_PACKAGE_LIBICONV if !BR2_ENABLE_LOCALE should
be changed, etc.

Also, do you have an idea of what is the state of the locale support in
musl ? Does musl provide the functions provided by libiconv ?

It would be good to take this opportunity to make sure the locale
support is OK.

Thanks,

Thomas
