I compiled perl 5.26.3 source code for RHEL from cpan link:

wget https://www.cpan.org/src/5.0/perl-5.26.3.tar.bz2

I compiled it with steps mentioned below:

    ./Configure -des -Dprefix=</path/to/install/>
     make
     make test
     make install

Then inside bin folder generated under </path/to/install/>

./perl -v

This is perl 5, version 26, subversion 3 (v5.26.3) built for x86_64-linux

What I see in Configure logs is it autodetected architecture as 64bit:

What is your architecture name [x86_64-linux]

I want to know, how to set option for 32bit so that I will get perl compiled binary of version 5.26.3 for 32bit. And should give result as : built for i686-linux instead of built for x86_64-linux
