I did a manual test build on gcc16 and I see:

(with make CLAMAV_MAKE_OPTS='V=1' BR2_JLEVEL=1 clamav)

libtool: link: /home/peko/tmp/buildroot/output/host/usr/bin/armv5-ctng-linux-gnueabi-gcc -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -pipe -Os -fno-strict-aliasing -o clamscan output.o getopt.o optparser.o actions.o misc.o clamscan.o manager.o  ../libclamav/.libs/libclamav.so -L/home/peko/tmp/buildroot/output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr/lib -L/usr/lib -lbz2 -lssl -lcrypto -lz -lm -ldl -lpthread -Wl,-rpath -Wl,/home/peko/tmp/buildroot/output/build/clamav-0.98.5/libclamav/.libs

collect2: error: ld returned 1 exit status

As the -L/usr/lib hints of, the bzip2 detection is failing. From
config.log:

configure:17633: checking how to link with libbz2

Thanks, but that doesn't work:

Applying buildroot-libtool-v2.4.patch using patch: 
patching file ltmain.sh
(cd /home/peko/tmp/buildroot/output/build/clamav-0.98.5/ && ... \
LIBBZ2_PREFIX=/home/peko/tmp/buildroot/output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr ac_cv_c_mmap_private=yes CONFIG_SITE=/dev/null ./configure
..
checking how to link with libbz2... /usr/lib/libbz2.so
checking for BZ2_bzDecompressInit in -lbz2... no
checking bzlib.h usability... yes
checking bzlib.h presence... yes

and it naturally still fails at the linking step.

Looking closer at the configure script I see we need to pass
ac_cv_libbz2_libs and ac_cv_libbz2_ltlibs instead. With that done it
works.

I'll cook a patch to do so.
