Building on aarch64 fails

[hpretl]

Building the latest version for x86_64 works fine, but the build on aarch64 fails with this error:

Please provide a bugfix that allow a successful build.

@RTimothyEdwards Any chance you can look into it?

[hpretl]

Maybe this helps? #19

[RTimothyEdwards]

Usually this kind of problem is fixed by just starting with aclocal, automake, and autoconf before running configure. However, if that doesn't work and PR #19 does, then I will do a complete test of the pull request and merge it if it does not affect the more common Ubuntu and Fedora compiles.

[hpretl]

OK, I'll test that and report back.

This solved the build fail, thanks!
