Failure to build on powerpc64le

Hi,

When trying to build your gem on powerpc64le, I get the following error:

I think this is because of the version of libmemcached you bundle: if you upgrade the bundled version to the latest (1.0.18) or use the system version if it's available, it should fix things. I can provide a pull request to bundle the latest version if that helps.

Are you building the gem from rubygems or from master?

[daxtens]

I was building from rubygems, I've just tried building from master and I get the same message. (I also tried building libmemcached by itself, and verified that any version short of 1.0.18 fails with an outdated config.{sub,guess}.)

i'm having this issue now for ubuntu on M1 (via docker). the correct system type is aarch64-unknown-linux-gnu and with newer config.guess and config.sub (e.g. /usr/share/automake-1.16/config.guess) the extension build works, but i'm not sure how to pass the type into the extension build from gem install memcached -v 1.8.0. is this possible?

[jakeonfire]

ended up switching to dalli

Having same issue. My company went to m1's across the board and now, we cannot build the Gemfile due to this.
