head -r329447: delete-old does not clean up after switching from WITH_CLANG_IS_CC to WITHOUT_CLANG_IS_CC

[Mark Millard]

[I historically experiment with system clang as the
system compiler for powerpc64 and powerpc. Thus the
context here is odd.]

As part of getting ready to test base/binutils and base/gcc I
changed how I build for powerpc64 to use WITHOUT_CLANG_IS_CC= .
I expected that after installing (updating) to a a local
directory tree that delete-old would remove the prior materials.
But it reports nothing as deleted and looking finds the files
still in place . . .

The relevant files from the prior build stayed in place.

Context:

# uname -apKU
FreeBSD FBSDFSSD 12.0-CURRENT FreeBSD 12.0-CURRENT  r329447M  amd64 amd64 1200058 1200058

I had been running -r329465 but was having panics in fork activity,
so there is a reversion to -r329447 between the old and new builds.
(I'm testing if I see problems in -r329447 .)
