There is no such file in current R:
gannet% ls
Makefile.in   Makefile.win* README        sunif.c       test.c

and README contains (correct) information on how to use it.

Where exactly did you see that recommended?  See R CMD LINK --help for how 
to use it (and not for this purpose).  I suspect you want

% gcc -o tr tr.o -L/path/to/libRmath -lRmath -lm
