    libbsd: fix compilation with musl 1.2.4
    
    musl 1.2.4 deprecated legacy "LFS64" ("large file support") interfaces so
    just having _GNU_SOURCE defined is not enough anymore.
    
    _LARGEFILE64_SOURCE has to be defined in the source, or CFLAGS can be used
    to pass -D_LARGEFILE64_SOURCE to allow to keep using LFS64 definitions.
    
    Fixes: fff878c5bcda ("toolchain/musl: update to 1.2.4")

  This library provides useful functions commonly found on BSD systems, and lacking on others like GNU systems, thus making it easier to port projects with strong BSD origins, without needing to embed the same code over and over again on each project.
