Build error when using `-no-crt` and `-o:speed` flags with `core:fmt` package

[englerj]

Context

• Operating System & Odin Version: Odin: dev-2022-10-nightly:775c9648 OS: Windows 11 Professional (version: 21H2), build 22000.978 CPU: Intel(R) Core(TM) i5-8600K CPU @ 3.60GHz RAM: 32702 MiB

Expected Behavior

Build succeeds.

Current Behavior

Build fails.

Failure Information (for bugs)

When using the core:fmt package, and building with both the -no-crt and -o:speed flags, the build fails due to an unresolved external symbol. When building with either the -no-crt or -o:speed flags (but not both), the build succeeds. When building with both flags and, additionally, the -use-separate-modules flag, the build will succeed.

Steps to Reproduce

package exe

import "core:fmt"

main :: proc()
{
    fmt.printf("{:v}, {:v}", "it's working", "it's working")
}

odin build -no-crt -o:speed

Failure Logs

... : error LNK2019: unresolved external symbol __gnu_h2f_ieee referenced in function fmt.fmt_quaternion ... : fatal error LNK1120: 1 unresolved externals

For what it's worth, I'm unable to replicate this on Linux (with the additional required -no-thread-local and -default-to-panic-allocator) as of the latest commit.
