It appears exim is trying to use features provided by
glibc's /lib/libresolv.so.2 that are not provided by 
uClibc.  Specifically, it is trying to use the functions
res_search() and dn_expand().

Quoting from the 'man' page:
    The res_search() function makes a query and waits for the
    response like res_query(), but in addition implements the
    default and search rules controlled by RES_DEFNAMES and
    RES_DNSRCH (see description of _res options below).

    The dn_expand() function expands the compressed domain name
    comp_dn to a full domain name, which is placed in the buffer
    exp_dn of size length. The compressed name is contained in a
    query or reply message, and msg points to the beginning of
    the message.
