MUSL compile fix for "unable to initialize decompress status for section .debug_info"

[brainstorm]

Seems like recent changes on the underlying musl/gcc toolchains affecting DWARF trigger build failures for debug (non --release builds).

For more context, the current rust-musl-make binutils version is 2.33.1, which apparently has compression for the debug symbols. see, i.e: TA-Lib/ta-lib-python#268 (comment)

I don't like to downgrade toolchain versions either, so I'll make the assumption that debug builds for MUSL are not very used ATM... my workflow is (re-)building and deploying AWS lambdas in --release mode for now.

Working (local) vs breaking (CI) compiler flags:

Looks fine to me.
