The ELDK now relies on Yocto, so it no longer has the funky
non-standard way of doing multilib. Also, we didn't mention that Yocto
toolchains/SDK are not suitable for usage with Buildroot. Therefore,
this commit rewords this part of the documentation to explain that
Yocto/OpenEmbedded SDKs cannot be used as external toolchains in
Buildroot, and why.

-* The ELDK toolchains have a completely non-standard custom mechanism

- GCC 'multilib' mechanism, the ARM ELDK uses different symbolic links
- to the compiler to differentiate between library variants (for ARM

- +CROSS_COMPILE+ environment variable. This non-standard behaviour
- makes it difficult to support ELDK in Buildroot.
