From: Jean-Paul Etienne <fractalclone at gmail.com>

Encountered the following while compiling matchbox-panel

mb-applet-wireless.o: In function `update_wireless':
.. matchbox-panel-0.9.3/applets/mb-applet-wireless.c:143: undefined reference to `log'
.. matchbox-panel-0.9.3/applets/mb-applet-wireless.c:143: undefined reference to `lrint'

fixed the issue by adding
1) #include <math.h> in mb-applet-wireless.c
2) -lm option to WIRELESS_LIB in applets/Makefile.in
