Log Message:
pkgtools/digest: Work around gcc compiler bug on VAX.

I think it has been fixed in gcc10, though, so let's limit the
versions to which this applies and extend it later if we find it's
still broken, rather than just carry it on indefinitely without
warning and a performance penalty of -O0 in a critical path on VAX.

PR 53947
