Hmm. Technically it is 'Recommended'. All my systems do have clang
and I don'y have a log from the failed build, all I know for certain
is that it tried to use clang when building skia, and failed because
clang does not (in current release) support my flags.
I'm guessing that your log can be interpreted as
should I build skia : yes (default)
do you have clang : no
ok, cannot build skia, issue a warning.
