indentation in Makefile

[Bruno Haible]

Apparently GNU make works also with spaces instead of tabs in continuation
lines of rule commands? But nevertheless it's more consistent to use tabs
here for indentation.

        Makefile: Tweak indentation.
        * Makefile: Use tab as first character in every line that contains rule
        commands.
