#12 Use Make variables in Makefile.am

[Joshua Judson Rosen]

Autoconf generates normal Make variables for each AC_SUBST'd Autoconf variable, and it's preferable to use the Make variables in stead of using the raw Autoconf variables directly: it means that the variables remain overridable after ./configure runs (though their default values are fixed by configure), that its possible for values to reference other Make or shell variables and be automatically resolved fully/cleanly (regardless of how many levels of indirection are used), etc.

cf. attached.
