  Log Message:
  -----------
  compile linux64x64 newspeak.cog.spur with clang

Reason: there's been some problem showing recently with gcc stack handling
The newspeak boostrap failed with this error:

    +/home/travis/build/OpenSmalltalk/opensmalltalk-vm/products/nscogspur64linuxht/bin/nsvm -headless ns-2019-10-23.64.image NewspeakBootstrap.st
    Segmentation fault (core dumped)

Also remove the -fwrapv compilation flag.
It was once necessary, but we should not
The -fwrapv tells the compiler to assume that integer overflow will wrap instead of being undefined behavior.
