Hmm, you found an issue in tools/build/mk/OptionalObsoleteFiles.inc. At
some point llvm-ar, llvm-nm, llvm-objdump and llvm-symbolizer got
promoted out of MK_CLANG_EXTRAS, so they always get installed. But in
OptionalObsoleteFiles they are still under MK_CLANG_EXTRAS, so if you
don't have that enabled, they are proposed for deletion.

I have MFCd a few additional changes to fix this, in:
https://svnweb.freebsd.org/changeset/base/362674

but this will have to be manually applied to your source tree, if you
don't want to get prompted anymore. Otherwise, simply ignore the
removal requests.
