fix internal compiler error in msys2 msys

[diamant3]

This is the error: https://pastebin.com/jHFLmRDL that I encountered when compiling the psptoolchain-allegrex scripts on the MSYS2 (MSYS) environment, and I think this PR is the most suitable. What I found out was that there was an error in the precompiled headers of the C++ standard library or something, but I'm not sure if this fix negatively affects others except the build time. I'm not a compiler expert or anything, so please enlighten me if there's an issue with my PR. Hopefully to be merged, thanks!

According to msys2 people specifically from biswa96 and mati865 on my msys2 discord post, that there is no bad effects of disabling the pch except the build time may be slower than usual.

Guess we'll just have to find out then. I'll do a quick test tonight, then merge.

Got it, Thank you!

This change does seem to cause some issues for me. If I build this, should I rebuild pspsdk and some of the tools as well? It seems this affects linking:

[100%] Linking CXX executable oceanpop
Stripping binary
Calling psp-fixup-imports
Error, no sceModuleInfo section found
make[2]: *** [CMakeFiles/oceanpop.dir/build.make:443: oceanpop] Error 1
make[2]: *** Deleting file 'oceanpop'
make[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/oceanpop.dir/all] Error 2
make: *** [Makefile:91: all] Error 2

I got this when building oceanpop.

Sorry i forgot this one. Yes, please rebuild the pspsdk and the tools too then install.

[sharkwouter]

Will do

Thanks wouter!

I just tested this once again with rebuilding the pspsdk and all packages and it worked fine. I've merged it now.
