see the archive, we just had a discussion about this

here is the summary:
http://www.openwall.com/lists/musl/2012/09/03/1

currently the easy way to work around broken code is
to add -D_GNU_SOURCE to the CFLAGS


exposing all stuff by default is not what you want:
many of the symbols are obsolete/broken, there are bsd
symbols not present in glibc and simple symbols that
violate the standard namespace (so they can easily cause
problems if made visible by default)
