[U-Boot] [PATCH] openrd: disable private arch memset, memcpy and libgcc

[Albert ARIBAUD]

The switch to private LIBGCC causes 'undefined instruction'
exception in at least the Open-RD Ultimate and Client, and
quite probably the Open-RD Base as well.

While debugging this issue, it appeared the switch to
architecture-optimized memset and memcpy also causes the
same exceptions.

Until a fix to private libgcc and architecture-optimized
memcpy and memset is mainlined, disable their use in all
openrd configurations.
