Hi,

good work! The minidlna package is fixed by your patch, but the 
libsidplay2 package needs some fixing:

[...]

checking whether the /home/bernd/buildroot/br2/output/host/usr/bin/
powerpc64le-linux-gcc linker (/home/bernd/buildroot/br2/output/host/opt/
ext-toolchain/powerpc64le-buildroot-linux-gnu/bin/ld -m elf64ppc) 
supports shared libraries... no
checking dynamic linker characteristics... GNU/Linux ld.so
checking how to hardcode library paths into programs... immediate
checking whether stripping libraries is possible... yes
checking if libtool supports shared libraries... no
checking whether to build shared libraries... no
checking whether to build static libraries... yes

which leads to

/home/bernd/buildroot/br2/output/host/opt/ext-toolchain/bin/../lib/gcc/
powerpc64le-buildroot-linux-gnu/5.4.0/../../../../powerpc64le-buildroot-

[_ZN12__sidplay2__6Player12interruptIRQEb]+0x58): call to

with -fPIC

powerpc64le-buildroot-linux-gnu/5.4.0/../../../../powerpc64le-buildroot-
linux-gnu/bin/ld: final link failed: Bad value

because configure is re-created during the build phase. The quote from 
configure comes from the second run of it.

I used this defconfig: http://autobuild.buildroot.net/
results/5d6/5d60bccbe024db240630845e15a3f15e8ddf0f01/defconfig
