+Subject: Do not load plugin from the $PWD
+
+I see no reason why this would make sense to look for plugins in the current
+directory. And when there are plugins there, it may actually be wrong

+Subject: QLibrary/Unix: do not attempt to load a library relative to $PWD
+
+I added the code in commit 5219c37f7c98f37f078fee00fe8ca35d83ff4f5d to
+find libraries in a haswell/ subdir of the main path, but we only need
+to do that transformation if the library is contains at least one
+directory seprator. That is, if the user asks to load "lib/foo", then we
+should try "lib/haswell/foo" (often, the path prefix will be absolute).
+
+When the library name the user requested has no directory separators, we
+let dlopen() do the transformation for us. Testing on Linux confirms
+glibc does so:
+
+$ LD_DEBUG=libs /lib64/ld-linux-x86-64.so.2 --inhibit-cache ./qml -help |& grep Xcursor
+   1972475:     find library=libXcursor.so.1 [0]; searching
+   1972475:       trying file=/usr/lib64/haswell/avx512_1/libXcursor.so.1
+   1972475:       trying file=/usr/lib64/haswell/libXcursor.so.1
+   1972475:       trying file=/usr/lib64/libXcursor.so.1
+   1972475:     calling init: /usr/lib64/libXcursor.so.1
+   1972475:     calling fini: /usr/lib64/libXcursor.so.1 [0]
