# see add.sh's own comment on USE_own_awk_symlink: when it's off (the
# default), THIS install never created $MP_PREFIX/bin/awk in the first
# place -- but autotools' own "make uninstall" rule removes it
# unconditionally regardless of whether THIS install actually put it
# there, so if some OTHER package's own "awk" (build-tools/onetrueawk,
# say) happens to be sitting at that same path when gawk gets removed,
# "make uninstall" would delete someone else's live binary with zero
# indication anything beyond "gawk was removed" happened. move it
# aside first and restore it after -- a plain "mv" of a nonexistent
# path is a harmless no-op either way, so this is safe to run
# unconditionally rather than needing to know in advance whether
# there's anything to protect.
#
# real "if" throughout, not "[ ... ] && cmd" chains: busybox ash (this
# system's own default SHELL) aborts the ENTIRE script the moment a
# bare "&&"/"||" list's own non-last command fails, not just skips the
# rest of that one list (see /etc/mpx.env's own identical warning, a
# real incident there too, and add.sh's own identical fix this same
# pass) -- "nothing to restore" is exactly that kind of non-last
# command legitimately returning false under set -e.
