[PATCH, RFC 09/22] crypto: lz4: don't build on ARM

[Arnd Bergmann]

It is not currently possible to build the LZ4 code on ARM, so let's
remove that option in Kconfig for now.

lib/built-in.o: In function `lz4_compress64kctx':
 lib/lz4/lz4_compress.c:339: undefined reference to `__ctzsi2'
lib/built-in.o: In function `lz4_compressctx':
 lib/lz4/lz4_compress.c:157: undefined reference to `__ctzsi2'
lib/built-in.o: In function `lz4hc_commonlength':
 lib/lz4/lz4hc_compress.c:102: undefined reference to `__ctzsi2'
 lib/lz4/lz4hc_compress.c:102: undefined reference to `__ctzsi2'
lib/built-in.o: In function `lz4hc_insertandgetwidermatch':
 lib/lz4/lz4hc_compress.c:230: undefined reference to `__ctzsi2'
