linuxtrack_find_library failed with problem: -4

Okay, I ran into another problem. When I build linuxtrackx-ir from source (610fd71b), the Wine Bridge doesn't want to load the 64-bit library anymore (tested with Falcon BMS and MSFS 2020).

[...]
DEBUG: Trying library: /usr/local/bin/..//lib/linuxtrack/liblinuxtrack.so.0
DEBUG: Library not found: /usr/local/bin/..//lib/linuxtrack/liblinuxtrack.so.0

DEBUG: Trying library: /usr/local/lib/linuxtrack/liblinuxtrack.so.0
DEBUG: Library not found: /usr/local/lib/linuxtrack/liblinuxtrack.so.0

What I don't understand is, the file is there but the log messages say Library not found...

❯ ll /usr/local/lib/linuxtrack/liblinuxtrack.so*
lrwxrwxrwx 1 root root  18 Nov 27 20:38 /usr/local/lib/linuxtrack/liblinuxtrack.so -> liblinuxtrack.so.0
lrwxrwxrwx 1 root root  22 Nov 27 20:38 /usr/local/lib/linuxtrack/liblinuxtrack.so.0 -> liblinuxtrack.so.0.0.0
-rw-r--r-- 1 root root 47K Nov 27 20:38 /usr/local/lib/linuxtrack/liblinuxtrack.so.0.0.0

Btw. the 32-bit library is now found without issues (tested in IL-2 Sturmovik 1946)...
