Bingo! Actually, double bingo!!

>From the docs for GNU Make:
"""
Because dollar signs are used to start make variable references, if you
really want a dollar sign in a target or prerequisite you must write
two of them, `$$' (see How to Use Variables). If you have enabled
secondary expansion (see Secondary Expansion) and you want a literal
dollar sign in the prerequisites lise [sic], you must actually write
four dollar signs (`$$$$').
