Added the HEXDUMP_PAGER #ifdef, since otherwise pager (which we do not need in this case) causes linking issue for boot1

This doesn't look right. Copy/paste error?

This looks OK to my eyes, modulo the comments about HEXDUMP_PAGER ifdef and how that gets defined... But I'm good either way with that...

stand/libsa/hexdump.c

We don't - at least not in libsa
the only usage there dumps 512 bytes which does not need pager.
