[Buildroot] [PATCH 1/2] package/gd: fix build when libiconv is enabled

[Bernd Kuhls]

First of two patches to fix
http://autobuild.buildroot.net/results/238/2386edb7f95920e84a35811a33f4333ee0a7a860/

gd links against libiconv if it is already built, depend on libiconv
to get reproducable builds.

readelf output without libiconv present:
$ output/host/opt/ext-toolchain/bfin-linux-uclibc/bin/bfin-linux-uclibc-readelf \
  -a output/staging/usr/lib/libgd.a | grep iconv
    15: 00000000    12 FUNC    GLOBAL HIDDEN     1 _iconv_open
    16: 0000000c    12 FUNC    GLOBAL HIDDEN     1 _iconv
    17: 00000018    12 FUNC    GLOBAL HIDDEN     1 _iconv_close

readelf output with libiconv present:
$ output/host/opt/ext-toolchain/bfin-linux-uclibc/bin/bfin-linux-uclibc-readelf \
  -a output/staging/usr/lib/libgd.a | grep iconv
