math library ordered wrong in compile commands

[unkadoug]

In order to complete the sequence
./bootstrap.sh
./configure
make
successfully, I first had to edit makefile.in so that "-lm" appeared after, not before, "$<" in the compile command lines. Otherwise, math library symbols were not found because the math library was not in line to be searched after the source file. FWIW, this is Ubuntu 18.04.

A corrective patch:
diff --git a/makefile.in b/makefile.in
index 2b8320c..15c3e8f 100644
