Log Message:
rust191: drop rust-analyzer from tools for NetBSD/powerpc.

The reason is https://github.com/rust-lang/rust/issues/148497:
rust-analyzer just outgrew the 24-bit word PC-relative offset
provided by the default relocation type.

With this the cross-build of rust for powerpc-unknown-netbsd now succeeds.
