package/babeld: disable for musl toolchains

Browse Source 
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.

Fixes:
