If the final targets depend on both "dtbs" and "dts/dt.dtb", and -j option is given to the command line, multiple threads descend into the dts/ directory, which causes build error.

Yamada-san, thanks, this patch is fantastic! It fixes the issue discussed under [1] (no longer need to suppress parallel DTC compiles) and also avoids the general double-compile of the DTC files that happened with my patch series. Tested it on a few TI ARMv7 OMAP-type EVMs and did not see any adverse effects.
