• Crank bootstraps

We need updated bootstraps for armv6, armv7, aarch64, powerpc64. rustc 1.34.2 (though probably 1.34.0 and 1.34.1 would also be ok) and cargo 0.35.0.

Sorry about that. I forgot to remove a bunch of patches. It builds
fine on 12.0/amd64 now so please retry. The distcache has probably also
caught up with my ~/public_distfiles for the tier 2 bootstraps now.

• www/seamonkey needs PORTREVISION bump for RUST option
• lang/rust fails check-plist due to orphaned files from bundled LLVM, see P260

Looks like there's some change in Altivec code:

Try changing use mem; to use crate::mem;.

[tobik]

• Bump revision of www/seamonkey too
• Attempt to fix build on powerpc64 (use mem -> use crate::mem)
• Apply band-aid and avoid restarting the LLVM build during the install phase and staging it badly (fix check-plist)

@jbeich Thanks for pointing this out. It seems that Rust is now always assuming that it needs to rebuild LLVM during install when it is not being built from a Git checkout. And since we are passing DESTDIR=${STAGEDIR} explicitly in do-install it gets copied into STAGEDIR the second time around.

[mikael]

It's ok on aarch64, I won't have time to check the other arches.

[pkubaj]

OK for me, I successfully built on 12.0-RELEASE/powerpc64.
