In very old Linux kernel (1.3.x) there is random.h but not RNDGETENTCNT. The random.h without RNDGETENTCNT was only used in the kernel internally. But at that time Linux Makefile didn't have "headers_install" target so user may copy all headers (including the internal ones) to /usr/include. It seems we should check RNDGETENTCNT explicitly if we want to support 1.3.x.
OK, I think that's ancient enough that we don't need to care about it, but on the other hand it's not impossible to believe that somebody could be using a custom Linux kernel that removed it. So let's keep the test for it.
