Build fails on CachyOS (Arch Linux)

[leap0x7b]

Couldn't pinpoint when the error occurs but here are the log files:

• binutils.log (compiles fine)
• gcc.log

Had to build it single-threaded since adding -j4 causes some issues.

Googled the error and found this:

I guess an issue with GCC 15.2.0. Try 15.1.0? I didn't know 16 was released either, I'll have to add that later. Still, I would expect Arch to be on the latest anyway...

[leap0x7b]

Got it built by adding CC=gcc-15 CXX=g++-15 before the make command. Seems like it's an issue with GCC 16. I think this issue could be closed when the fix got merged.
