To fix that, we disable libcilkrts when thread support is not available. This issue was not noticed until now, because we only regularly build a no-thread toolchain for ARM, and libcilkrts was enabled on ARM only starting in gcc 7.x. This fixes the build of no-thread toolchains on architectures where libcilkrts is supported, i.e x86/x86-64, ARM and Sparc.
