Automake is written in Perl so it does not really get "compiled" in the
usual sense.

My first guess is that perl is not installed on the host (risc-v)
system.  Specifically, these files begin with #!/usr/bin/perl (or
similar - depends on configure tests) and that program is not
available when you run them.

However, I took a quick look at Automake's configure script and it
appears it detects perl only on the build system and then installs
that filename into the installed scripts.  So I think it will not
work out of the box unless a supported perl version is installed
at the same location on both the build and host machines.

Cheers,
