Description
### Bug Summary
On installing LMMS using portage, the resultant build I got couldn't load the effects giving errors like
```"Cannot load library /usr/lib/ladspa/sc1_1425.so: (/usr/lib/ladspa/sc1_1425.so: wrong ELF class: ELFCLASS32)"```
I thought maybe my kernel couldn't execute 32 bit binaries but I am able to run everything flawlessly using the AppImage.
#### Steps to reproduce
Emerge lmms with abi flags ```abi_x86_64``` and ```abi_x86_32``` or as ```ABI_X86="64 32"``` in ```/etc/portage/make.conf``` in Gentoo Linux or its derivatives (like Sabayon Linux) to build 32 and 64 bit binaries.
#### Expected behavior
The requested effects were expected to load without any verbose output or a dialog box.
#### Actual behavior
The requested effects couldn't be processed since the detection wrong ELF class prevented loading them.
#### Screenshot
#### Affected LMMS version
1.2.2

Research direction
Start by reproducing the Gentoo Portage build with ABI_X86 set to 64 and 32, then inspect how LMMS discovers and loads the LADSPA libraries under /usr/lib and /usr/lib64. Done means the requested effects load without ELFCLASS32 errors or missing Carla-library messages.
