bug in 'iconvme' module

[Bruno Haible]

Simon,

On MacOS X with GNU libiconv module, the iconvme module exhibits a build
failure:

Making all in lib
make  all-am
gcc -DHAVE_CONFIG_H -I. -I../../../megatestdir/iconvme/lib -I..     -g -O2 -c 
../../../megatestdir/iconvme/lib/iconvme.c
../../../megatestdir/iconvme/lib/iconvme.c: In function `iconv_alloc':
../../../megatestdir/iconvme/lib/iconvme.c:134: warning: passing arg 2 of 
`libiconv' from incompatible pointer type
rm -f libgnu.a
ar cru libgnu.a iconvme.o -liconv
ar: -liconv: No such file or directory

make[3]: *** [all] Error 2

IMO you need to add $(LTLIBICONV) to lib_LDFLAGS, not lib_LIBADD.
And also, use $(LIBICONV) instead of $(LTLIBICONV) when libtool is not used.
That's why you introduced GL_COND_LIBTOOL conditional, no?
