FYI: useless tabs before variable definitions

[Pavel Roskin]

Hello!

When you modify Automake and commit your changes it's often a good idea to
run the new automake in the automake working directory and check the
difference in Makefile.in.

This trick would show you that the variables "host_alias" and others are
now preceeded by tabs. This is not good.

ChangeLog:
        * header-vars.am: Remove tabs before variable definitions.
