RE: big endian builds

Nightly verification script modifies CONFIG_CROSS_COMPILE in the .config file before build Linux - little or big endian doesn't matter, so path to tools is always correct. It sets full path in .config, instead of prepending PATH. CONFIG_CPU_BIG_ENDIAN is set accordingly. 8< # G

The problem is with CONFIG_CPU_BIG_ENDIAN=y we still needed .config fixup to override the the defconfig prefix to arceb-linux- So remove these from defconfig and let user pass this via CROSS_COMPILE environment var or use the default for ENDIAN (per previous patch) No other arch carries them in d
