+Subject: [PATCH] link sublibs against liblzma as needed
+
+The coredump/elf32/elf64/elfxx libs use lzma funcs but don't link against
+it.  This produces sub-shared libs that don't link against lzma and can
+make the linker angry due to underlinking like so:
+
+libtool: link: x86_64-pc-linux-gnu-gcc -O2 -march=amdfam10 -pipe -g \
+	-frecord-gcc-switches -Wimplicit-function-declaration -fexceptions \
+	-Wall -Wsign-compare -Wl,-O1 -Wl,--hash-style=gnu \
+	-o .libs/test-coredump-unwind test-coredump-unwind.o  \
+	../src/.libs/libunwind-coredump.so ../src/.libs/libunwind-x86_64.so
+../src/.libs/libunwind-coredump.so: error: undefined reference to 'lzma_stream_footer_decode'
+../src/.libs/libunwind-coredump.so: error: undefined reference to 'lzma_index_buffer_decode'
+../src/.libs/libunwind-coredump.so: error: undefined reference to 'lzma_index_size'
+../src/.libs/libunwind-coredump.so: error: undefined reference to 'lzma_index_end'
+../src/.libs/libunwind-coredump.so: error: undefined reference to 'lzma_index_uncompressed_size'
+../src/.libs/libunwind-coredump.so: error: undefined reference to 'lzma_stream_buffer_decode'
+collect2: error: ld returned 1 exit status
+
+So add LIBLZMA to the right LIBADD for each of these libraries.
