[Buildroot] [PATCH 1/1] package/libdcadec: Add -fPIC to static build, enable shared build

[Bernd Kuhls]

Adding -fPIC fixes
http://autobuild.buildroot.net/results/a19/a19023e094cbed491444665d6839a9e65a8eee6c/

http://autobuild.buildroot.net/results/8ce/8ced16874255ace4923f6b8888c3fca07f28b804/

The upstream Makefile also allows building a shared library if
CONFIG_SHARED=1 is added to _BUILD_CMDS.
