This logic is required for cross LLVM toolchains built against glibc with its libcrypt disabled because compiler-rt requires a crypt.h header for its sanitizers, leading to a circular build dependency situation: libxcrypt -> compiler-rt -> libxcrypt To break this circular dep other cross-compilation build systems like Yocto have disabled compiler-rt sanitizers entirely [1] or a crypt.h header might be copied into the compiler-rt sources. A better solution than the above two is to directly be able to build libxcrypt before compiler-rt in the cross toolchain setup steps which is what this addition enables.
