Disable -fstack-clash-protection on riscv64:

not supported even by GCC 7.3.1 on this architecture.

Apparently it requires architecture-specific support.  In any case it
does not work with GCC 7.3.1 on riscv64:

stage3:/# gcc --version

gcc: error: unrecognized command line option '-fstack-clash-protection'; did you mean '-fstack-protector'?
gcc: fatal error: no input files
compilation terminated.
