Building babeld with a musl toolchain fails with: ld: read-only segment has dynamic relocations This happens because babeld uses text relocations (textrels), which are not supported by the musl dynamic loader and would cause a runtime crash (segmentation fault). Since Buildroot passes '-ztext' to detect these unsafe relocations at build time, disable babeld entirely for musl configurations.
