the document about gnu makefiles has a tiny (but significant) mistake

the document claims GNU `make` looks for `GNUMakefile` (uppercase `M`), its actually `GNUmakefile` (lowercase `m`) ``` $ touch GNUMakefile $ make make: *** No targets specified and no makefile found. Stop. $ touch GNUmakefile $ make make: *** No targets. Stop. ```
