Distributed release files can only compile for musl

[addisoncrump]

See: astral-sh/ruff#9368

It seems that binstall (which pulls from GitHub since the release) installs the musl copies distributed in the latest release, but the released files can only build musl-targeting fuzzers.

I would expect that the distributed files should be compatible with any toolchain.

I have tested all musl binaries (0.11.2-0.12.0), and they all have this issue.

And, this is due to the following code using the target that is used to build cargo-fuzz itself as the default target.

cargo-fuzz/src/utils.rs

Lines 1 to 4 in 351f11d

	/// The default target to pass to cargo, to workaround issue #11.
	pub fn default_target() -> &'static str {
	current_platform::CURRENT_PLATFORM
	}

The more correct way here is to get host triple from the output of cargo --version --verbose, like this.

(Workaround is passing --target x86_64-unknown-linux-gnu to cargo fuzz.)

The more correct way here is to get host triple from the output of cargo --version --verbose, like this.

However, to provide the fully same behavior as the default target selection in cargo, a library such as cargo-config2 is needed because we need to handle config while handling its hierarchical structure and environment variables.

Filed #365 to fix this.

Bump, this just happened again.
