nbase MD5 and SHA1 break static builds

[David Fifield <david () bamsoftware com>]

Hi,

I get this error after "make distclean", "./configure", and "make static":

I see that in nbase/configure.ac I see that the MD5 and SHA1 files are
always included:

dnl We always want some of our files
...
AC_LIBOBJ([nbase_md5])
AC_LIBOBJ([nbase_sha1])

Maybe it has to be made conditional?
