Makefile updates

Several, mostly internal, things changed. Most notably, the install
directories are extended (we'll need this to install the new library).
Also, explicit rules for creating .c and .o files are added.

Location:

lm-sensors/trunk

Files:

• Makefile (modified) (8 diffs)
• i2c/detect/Module.mk (modified) (2 diffs)
• kernel/include/sensors.h (modified) (1 diff)
• src/sensors.h (modified) (1 diff)
