Hi,

it seems we hit the _gp linker bug again which Peter planned to 
investigate: http://patchwork.ozlabs.org/patch/312275/

Here is the minidlna/config.log snippet regarding the current autobuild 
error. Sorry, no solution from me this time.

configure:9318: checking for avformat_open_input in -lavformat
configure:9343: /home/buildroot/output/host/usr/bin/nios2-linux-gnu-gcc -o 
conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64
  -pipe -Os  -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=
64  conftest.c -lavformat   >&5
/home/buildroot/output/host/opt/ext-toolchain/bin/../lib/gcc/nios2-linux-
gnu/4.7.3/../../../../nios2-linux-gnu/bin/ld: /home/buildroot/out
put/host/usr/nios2-buildroot-linux-gnu/sysroot/usr/lib/crt1.o: undefined 
reference to symbol '_gp'
/home/buildroot/output/host/opt/ext-toolchain/bin/../lib/gcc/nios2-linux-
gnu/4.7.3/../../../../nios2-linux-gnu/bin/ld: note: '_gp' is defined in DSO
 /home/buildroot/output/host/usr/nios2-buildroot-linux-
gnu/sysroot/usr/lib/libvorbisenc.so.2 so try adding it to the linker 
command line
/home/buildroot/output/host/usr/nios2-buildroot-linux-
gnu/sysroot/usr/lib/libvorbisenc.so.2: could not read symbols: Invalid 
operation
