On Linux, Yagi fails to load processor definitions if the `Ghidra` folder is a symbolic link

[trou]

With release 1.3.0, on Linux 64 bit, Yagi outputs [Yagi] ERROR : No sleigh specification for sparc:BE:32:default when the path ~/.idapro/plugins/Ghidra is a symbolic link to the real folder.

Things work correctly when Ghidra is copied to ~/.iidapro/plugins. This is confirmed by the following traces obtained with strace -f -e file ida file.idb:

Not working:

$ grep Ghidra test
