Last time I checked, it was the printf("\n") occurences that were not allowed by klibc. Had to replace them by fprintf(stdout, "\n") ...
I guess I reported that to you or Joe already. I don't know if recent klibc are more tolerent.
Anyway, distributors need to package klibc-linked libdevmapper.a and libsysfs.a for programs like the multipath-tools to ship without the libs. Plus klibc.a and headers ... all in sync.
Seems quite hard, so I guess I'll package the libs for some times unless someone has better insights. /sigh/
That said, distributors will have the choice to trim the package down, as I will include in 0.3.4 glibc-build / dynamic linking Makefiles. This was asked by Suse.
