[OE-core] [PATCH] apmd: fix build with static libraries disabled

[Ross Burton]

apmd was using foo.o in Makefile dependencies but if libtool is being used then
those are the statically linked intermediate files.  When static libraries are
globally disabled they won't be generated by libtool-cross so the build fails.
Instead, use the libtool intermediate wrapper .lo files so the build succeeds.

+When building use the libtool intermediate .lo files instead of explicitly using
+the .o files. Under libtool foo.lo is the libtool intermediate wrapper, foo.o is
+a static build, and .libs/foo.o is a shared build.
+
+If static libraries have been disabled globally then libtool won't generate them
+and explicit references to foo.o won't be satisfied.
