toolchaintechnotes: gcc -dumpmachine is similar to config.guess, but not same
Many distros have some customized things in gcc -dumpmachine. RHEL uses
x86_64-redhat-linux-gnu, and Ubuntu uses x86_64-linux-gnu ("vendor"
field omitted). So don't use "same" here, and also mention the "vendor"
field is sometimes omitted.
