I added the code in commit 5219c37f7c 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
