Installed kernel leaves "build" directory inside /usr/lib/modules/<ver-pkgbase>/build

### Same-issue check Yes ### Linux Distribution Archlinux ### Kernel version 7.0-rc5 (happened before as well) ### What happened? Hi, I've noticed I always have a ~180mb build directory inside the /usr/lib/modules folder of the built kernel. The Kernel that Arch delivers has no such kernel. I use modprobed, so without that directory, the kernel and modules has under 30mb, while the arch kernel has 170mb. Though the build directory makes my kernel ironically bigger than the Arch kernel. ``` --- /usr/lib/modules --------------------------------------------------------------------------------------------------- 210.9 MiB [#################] /7.0.0-rc5-273-tkg-linux-mainline-llvm-minimal 169.6 MiB [############# ] /6.19.9-arch1-1 ``` ``` --- /usr/lib/modules/7.0.0-rc5-273-tkg-linux-mainline-llvm-minimal ----------------------------------------------------- /.. 181.3 MiB [#################] /build 15.2 MiB [# ] vmlinuz 13.4 MiB [# ] /kernel 184.0 KiB [ ] modules.symbols.bin 156.0 KiB [ ] modules.symbols 144.0 KiB [ ] modules.alias 144.0 KiB [ ] modules.alias.bin 140.0 KiB [ ] modules.builtin.modinfo 68.0 KiB [ ] modules.builtin.alias.bin 36.0 KiB [ ] modules.dep.bin 28.0 KiB [ ] modules.dep 12.0 KiB [ ] modules.builtin.bin 12.0 KiB [ ] modules.builtin 8.0 KiB [ ] modules.order 4.0 KiB [ ] modules.devname 4.0 KiB [ ] modules.softdep 4.0 KiB [ ] modules.weakdep 4.0 KiB [ ] pkgbase ``` I feel like the build directory has no business here. It's not a LOT of megabytes, so it's not an issue that is in any way critical, but it's still a little bit silly :) ### Relevant logs [system-info.txt](https://github.com/user-attachments/files/26293793/system-info.txt) [customization.cfg.txt](https://github.com/user-attachments/files/26293792/customization.cfg.txt) [prepare.log.txt](https://github.com/user-attachments/files/26293794/prepare.log.txt) [git_work.log.txt](https://github.com/user-attachments/files/26293795/git_work.log.txt) ### My Favorite type(s) of frog Frog, Wood Frog (Lithobates sylvaticus)
