I've merged this patch with one I had locally updating to a later
commit.

I adjusted this patch so that we kept the previous rust-bootstrap since
rust-bootstrap <at> 1.74 doesn't build on all the architectures.  I found it
failed on aarch64 and powerpc64le and the build is still ongoing for
riscv64.  I haven't tested it on any of the 32-bit systems yet.

This patch I dropped since we can't get rid of the intermediate rust
versions yet.  I instead wrote a different patch merging
rust-bootstrap-1.74 into the chain so that rust-1.75 will build with
rust-bootstrap-1.74 if it is supported and rust-1.74 otherwise.

This one I modified slightly to keep the *-bootstrap names since I
didn't drop them from rust-bootstrap-1.54.

This one I didn't apply since we still need the in between versions.

>   gnu: rust: Use gexps.

This one didn't apply, but I'd be happy to use if you fixed it up.
