* Makefile ($(objpfx)version-info.h): Generate from Banner files.
* version.c (banner): Add contents of version-info.h to string.
* Makerules: If $($(subdir)-version) is available name versioned
shared library according to this value instead of glibc's version.
* libio/Banner: New file.
* elf/eval.c (funcall): Write error message in case function is
not found.
(eval): Recognize `_' in names.
