IIUC, this appears to have broken the Go compiler. Unsetting 'CC' makes it work again. IIUC this wasn't a problem with normal Fedora setup for ccache, because that doesn't set 'CC', it just puts the ccache 'gcc' binary into $PATH.
It looks like its a limitation of "Go" - it doesn't like it when "CC" contains multiple words - it drops everything except the first word. So when we set CC="ccache cc", go just runs "ccache $args" instead of "ccache cc $args"
MinGW (or at least the way we do MinGW builds) has a similar issue. I've posted a workaround: https://www.redhat.com/archives/libvir-list/2018-April/msg01000.html -- Andrea Bolognani / Red Hat / Virtualization
