Bug#785365: clang-3.5: undefined reference to `__stack_chk_guard'

[Jakub Wilk]

Package: clang-3.5
Version: 1:3.5.2-1
Severity: important
Control: affects -1 src:afl

I can't build programs with stack protector enabled on some 
architectures (at least kfreebsd-*, powerpc, ppc64el):

$ echo 'int main(int argc, char **argv) { int x[99]; return 0; }' > test.c
$ clang-3.5 -fstack-protector-strong test.c
/tmp/test-9eb12a.o: In function `main':
test.c:(.text+0x11): undefined reference to `__stack_chk_guard'
test.c:(.text+0x2f): undefined reference to `__stack_chk_guard'
clang: error: linker command failed with exit code 1 (use -v to see invocation)
