Hi, With recent change of skalibs configure script, there's a false positive case.
`choose l` use linker to test function if exists. But actually I observe that, ``` /usr/bin/ld: src/librandom/random_string.lo: in function `random_string': ./src/librandom/random_string.c:26: warning: getrandom is not implemented and will always fail ``` ld returns zero, even it knows "xxx is not implemented and will always fail". I think the LDFLAGS should be appended with "-Wl,--fatal-warnings", so that ld returns non-zero in such case. I only observe such case on GNU Hurd/K*BSD actually. I'm thinking if only these non-linux systems have such confused behaviour(why it links successfully at all...) -- Shengjing Zhu
