Support caching with rustc's --sysroot argument

[bluecmd]

Hi,

I'm trying to use sccache to speed up compilation of OpenWrt which in my particular configuration ends up building a Rust toolchain.

My sccache stats after a few builds give me this:

Compile requests                   1529
Compile requests executed           268
Cache hits                          266
Cache hits (C/C++)                   73
Cache hits (Rust)                   193
Cache misses                          0
Cache timeouts                        0
Cache read errors                     0
Forced recaches                       0
Cache write errors                    0
Compilation failures                  0
Cache errors                          2
Cache errors (Rust)                   2
Non-cacheable compilations            0
Non-cacheable calls                1187
Non-compilation calls                74
Unsupported compiler calls            0
Average cache write               0.000 s
Average compiler                  0.000 s
Average cache read hit            0.007 s
Failed distributed compilations       0

Non-cacheable reasons:
--sysroot                           915
crate-type                          212
-                                    38
missing input                        22

Cache location                  Local disk: "/var/tmp/openwrt-sccache/"
Use direct/preprocessor mode?   yes
Version (client)                0.8.1
Cache size                          147 MiB
Max cache size                       10 GiB

My understanding is that the majority of calls are not being cached as they specify an alternative sysroot. Looking at sccache source code I found this:

https://github.com/mozilla/sccache/blob/9958e7c8a023b39df2c56073748d37a77febac03/src/compiler/rust.rs#L1024-L1029

I assume the TooHard family is a form of "not implemented", if so this all makes sense so far.

As I have no knowledge how sccache works internally, I do not know how feasible it would be to add support for caching these types of calls. My hope is that it can be done simply by adding sysroot to some kind of hash somewhere to prevent collisions, but that may be too naive. I'll defer to the maintainers.

Example invocation that openwrt seems to use:
