Fixed:
make: *** No rule to make target `/path/to/sysroot/4.9.0/include/stddef.h', 
needed by `crc32.o'.  Stop.
make: *** Waiting for unfinished jobs....
ERROR: oe_runmake failed

This happens when upgrade gcc from 4.9.0 to 4.9.1, and the .depend isn't
regenerated when recompile, the content of it are:

[snip]
crc32.o: /path/to/sysroot/4.9.0/include/stddef.h
[snip]

And Makefile includes the .depend file if it exists, so there would be
errors when /path/to/sysroot/4.9.0/include/stddef.h doesn't exist.

Remove .*.d (a few .d files, its Makefile uses this wildcard) will fix
the problem.
