[Buildroot] [PATCH 5/8] samba4: remove dependency on specific C libraries

[Romain Naour <romain.naour@gmail.com>]

Thomas, All,

I'm not able to select samba4 with a musl toolchain.
Samba4 needs BR2_TOOLCHAIN_HAS_NATIVE_RPC which is not selected/detected with
internal/external toolchains.

So, no samba4 with musl for the moment ;-)

Best regards,
Romain
