Local binary linux wasmvm panic

[TxCorpi0x]

Description

This pull request refactors and simplifies the logic for setting up the musl toolchain when building for Linux platforms in build/tx-chain/build.go. The most important change is the introduction of a new helper struct and function to encapsulate the configuration for musl-based toolchains, reducing code duplication and improving maintainability. The main build logic is updated to use this new abstraction.

Refactoring and toolchain configuration:

• Introduced a new linuxMuslToolchain struct and the linuxMuslToolchainFor function to encapsulate all musl toolchain paths and configuration for different Linux architectures, replacing duplicated logic and hardcoded values.
• Updated the buildTXdInDocker function to use the new linuxMuslToolchain abstraction, greatly simplifying the logic for setting up compiler and library paths, Docker volumes, and environment variables for musl-based static builds.

Build logic improvements:

• Improved comments and error handling to clarify why musl and static linking are required for Docker builds, and to ensure unsupported platforms are handled gracefully.

FIXES

Incompatible build wasm causes SIGABORT panics in wasmvm when the blockchain node is built without the needed muslc flags and properties which is needed in the Alpine blockchain node.

Reviewers checklist:

• Try to write more meaningful comments with clear actions to be taken.
• Nit-picking should be unblocking. Focus on core issues.

Authors checklist

• Provide a concise and meaningful description
• Review the code yourself first, before making the PR.
• Annotate your PR in places that require explanation.
• Think and try to split the PR to smaller PR if it is big.

build/tx-chain/build.go line 217 at r1 (raw file):

// targetPlatform is used for all Path() lookups so local and in-Docker builds use the same toolchain.
func linuxMuslToolchainFor(targetPlatform txcrusttools.TargetPlatform) (linuxMuslToolchain, error) {
	switch targetPlatform {

This is already checked:

targetPlatform.OS == txcrusttools.OSLinux

So, I think this part is not needed.

build/tx-chain/build.go line 229 at r1 (raw file):

	switch targetPlatform.Arch {
	case txcrusttools.ArchAMD64:
		gccBin, wasmLib, wasmSubdir = "bin/x86_64-linux-musl-gcc", "lib/libwasmvm_muslc.x86_64.a", "/x86_64-linux-musl/lib/libwasmvm_muslc.x86_64.a"

Again, everything except x86_64 and aarch64 are duplicated. We can simply get the architecture in a variable and format those paths
