Remove unnecessary patches

[direc85]

Building Rust tested with patched LLVM 16. Still requires building Rust in Platform SDK chroot - build still hangs on x.py (iirc) with mb2 --target or Sailfish SDK sfdk build.

[SailfishOS-4.6.0.11EA-aarch64] whisperfish $ rustc --version --verbose   
rustc 1.75.0-nightly (82e1608df 2023-12-21) (built from a source tarball)
binary: rustc
commit-hash: 82e1608dfa6e0b5569232559e3d385fea5a93112
commit-date: 2023-12-21
host: i686-unknown-linux-gnu
release: 1.75.0-nightly
LLVM version: 16.0.6

LLVM 16 seems to be fine here, but building Whisperfish fails:

RPM build errors:
    Bad exit status from /var/tmp/rpm-tmp.J3YQ7u (%build)

Pushing this here anyway so others can see where I'm currently stuck at.
