Nak for MIPS. On MIPS Kconfig already always sets one of CPU_BIG_ENDIAN
and CPU_LITTLE_ENDIAN depending on platforms and where both endianess are
supported by a platform, user choice:
config FOO
bool "foo"
select SYS_SUPPORTS_LITTLE_ENDIAN
config FOO
bool "foo"
select SYS_SUPPORTS_BIG_ENDIAN
select SYS_SUPPORTS_LITTLE_ENDIAN
[...]
choice
prompt "Endianess selection"

Some MIPS machines can be configured for either little or big endian
byte order. These modes require different kernels and a different
Linux distribution. In general there is one preferred byteorder for a
particular system but some systems are just as commonly used in the
one or the other endianness.
config CPU_BIG_ENDIAN
bool "Big endian"
depends on SYS_SUPPORTS_BIG_ENDIAN
config CPU_LITTLE_ENDIAN
bool "Little endian"
depends on SYS_SUPPORTS_LITTLE_ENDIAN

So I think you can just drop the MIPS segment from your patch.
