Reduce the disc1.iso image size by setting WITHOUT_CLANG=1 for the
'system' target. Since clang is not enabled by default for releng/9.2,
this has no user visible changes by default.
This brings 9.2-R* well enough below the 700MB mark so that we do not
need to be concerned with it fitting on standard CD-ROM medium.
This is a direct commit to releng/9.2, pending further review for head/
and stable/9/.
