target-c-int-width: invalid type: string "32", expected u16

[ag-wnl]

My custom triple target looks like:

{
  "llvm-target": "x86_64-unknown-none",
  "data-layout": "e-m:e-p270:32:32-p271:32:32-p272:64:64-i64:64-i128:128-f80:128-n8:16:32:64-S128",
  "arch": "x86_64",
  "target-endian": "little",
  "target-pointer-width": "64",
  "target-c-int-width": 32,
  "os": "none",
  "executables": true,
  "linker-flavor": "ld.lld",
  "linker": "rust-lld",
  "panic-strategy": "abort",
  "disable-redzone": true,
  "features": "-mmx,-sse,+soft-float",
  "rustc-abi": "x86-softfloat"
}

When I run:
cargo bootimage

I get:
error: error loading target specification: target-c-int-width: invalid type: string "32", expected u16 at line 11 column 28

however, the trace of the error takes me to bootloader-0.9.31/x86_64-bootloader.json - where it's occuring as it has "32" as the target-c-int-width. I tried updating to the latest bootloader crate but everything breaks on build for some reason so it's unusable.

This is what I'm running:

We'll need to release a fix for the 0.9.x series.
