That is a heavy dependency. As you noted in another message, it also make the 
autobuilder skip this package. I suggest to download just spidev_test.c from 
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/plain/Documentation/spi/spidev_test.c?id=$(SPIDEV_TEST_VERSION), 
and make it depend on BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_15 (as of v3.17). This 
solves both the autobuilder issue, and the toolchain headers dependency.
