you can use HOST_CC to specify the host compiler when building tools;
currently you can use HOST_CC=pcc to build tools with HAVE_PCC= but it
cannot build gcc :)

I built most of a distribution (using gcc) with pcc-built tools (except
for gcc, built separately) but the nbsort coredumps on large files (eg
sorting the setlists) which is the code generation bug I have identified
but not pinned down any further..

..as there is another issue blocking me, we have recently switched to
using --sysroot which pcc does not properly support and I've been busy
this week with other things
