libcompiler_rt implements certain functions that clang and gcc emit calls to as part of their codegen (e.g. for extended width math). Build it without stack smashing protection (SSP, -fstack-protector) in order to support building binaries without SSP, especially the dynamic linker. Besides, SSP is probably not very valuable in this library. Reviewed by: arichardson, dim, kib Sponsored by: Dell EMC Isilon Differential Revision: https://reviews.freebsd.org/D27786
