How to install on linux x86 ?

Hello!
Is it possible to run mkcert in x86 OS?
There is no pre-built binary for x86: https://github.com/FiloSottile/mkcert/releases
Brew needs x64.
Building from source code does not work also.

I tried to make pem-files on x64 system and then copy them to the x86 system,
but that does not work - browser does not like it very much: NET::ERR_CERT_AUTHORITY_INVALID

Adding certificate to the trusted also not work.

So, as I understand you need to run "mkcert -install" to make it work properly.

But how to run "mkcert -install" on the x86 ? :)

My OS is "Ubuntu 14 x86"
