I still cannot reproduce your issue...  To check, I have built world
with CPUTYPE=athlon-xp, verified it used "-O2 -pipe -march=athlon-xp" as
compilation flags for the world stage, and installed the resulting clang
executables.

Those clang executables do not exhibit the same problem as yours do;
they can build tblgen (during the bootstrap-tools stage) fine.

I suggest you comment out the CPUTYPE macro in make.conf for now,
rebuild your world with gcc, and then rebuild it with clang again, to
see if the issue goes away.
