 339                   Build the toolchain with parallel make jobs.
 340                   This speeds up the toolchain build on SMP machines, but may
 341                   break the build for certain toolchain versions.
 342
 343                   If you say Y, toolchain build might break.
 344                   Before reporting build bugs, set this to N and re-run the build.
