It looks good on the outside, but on closer inspection, some things do appear strange.

* export CFLAGS=".. -lm": -l is not a compile flag, it's a linker flag...
* passing "-lm" to make is outright wrong; make's -l argument takes a floating point number.
* we should not be needing the .la file, since only a shared library is shipped, and it already encodes the libm.so dependency in the ELF.

I will be accepting this anyway, but only to get the source update in a fast fashion.
