PSP: Allow building tests in parallel

[sharkwouter]

Without this change using the -j flag while building the tests causes errors.

Description

The PSPSDK has been updated to allow for setting the target directory of EBOOT.PBP file. We can use this to make it possible to use the -j flag while building them. Right now this still causes errors.

I'll see if I can do the same for SDL3

I don't think parallel build are completely fixed.

Apply this patch to enable parallel builds on ci.

[sharkwouter]

I'll take a look, see if I can fix it.

[sharkwouter]

@madebr I don't understand, that workflow is failing while doing things that are not in the CMakeLists.txt file after merging this PR.

[madebr]

My logs look similar to the logs of the most recent run of libsdl-org/SDL's main branch?
What difference are you seeing?
Only thing my patch does, is remove the -j1 while building.

[madebr]

I think the issue with SDL3 is that the examples directory contains a copy of the CMakeLists.txt of tests

[sharkwouter]

Oh, I see. I did not fix this same issue for examples. I wasn't aware that worked the same way.

@madebr I made another PR which fixes this: #11392
