tools include: Adopt strstarts() from the kernel
Replacing prefixcmp(), same purpose, inverted result, so standardize on
the kernel variant, to reduce silly differences among tools/ and the
kernel sources, making it easier for people to work in both codebases.
And then doing:
if (strstarts(option, "no-"))
Looks clearer than doing:
if (!prefixcmp(option, "no-"))
To figure out if option starts witn "no-".
