make DESTDIR broken

[Zalewa]

Problem 1: make DESTDIR=../AAA install will install to AAA, not ../AAA

$ file AAA
AAA: cannot open `AAA' (No such file or directory)

$ file ../AAA
../AAA: cannot open `../AAA' (No such file or directory)

$ make DESTDIR=../AAA install
Making install in services
(logs ...)

$ file ../AAA
../AAA: cannot open `../AAA' (No such file or directory)

$ file AAA
AAA: directory

Notably, wget 1.21.3 has an identical problem, but zlib 1.2.13 does it as expected - the AAA directory is created at ../AAA.

Problem 2: make DESTDIR fails when the directory is not absolute:

$ make DESTDIR=AAA install
Making install in services
make[1]: Wejście do katalogu '/data/foss/icecc/_build/icecream-debug/services'
make[2]: Wejście do katalogu '/data/foss/icecc/_build/icecream-debug/services'

Usage: /data/foss/icecc/_build/icecream-debug/libtool [OPTION]... [MODE-ARG]...
Try 'libtool --help' for more information.
libtool:   error: 'AAA/opt/icecc/icecream_debug_amd64/lib' must be an absolute directory name

make[1]: Opuszczenie katalogu '/data/foss/icecc/_build/icecream-debug/services'

Workaround: Run it with an absolute path like this: make DESTDIR=$(cd .. && pwd)/AAA install
