check for iconv only once (#7873)
It is enough to check for iconv
dependencies once in the eglib/configure
- just use the generated libtool
library file to automatically
add additional dependencies (if any).
While here, make sue libeglib.a
has libraries returned by LTLIBTOOL
as a libtool dependency.
