Can't compile on newest Ubuntu if -lz is not at the end

[mfonville]

zlib dev headers did change their behaviour in an evil way, which forces -lz now to be at the very end of the compile command.

Otherwise it fails with

./libsparse.a(output_file.o): In function `gz_file_close':
output_file.c:(.text+0x689): undefined reference to `gzclose'
./libsparse.a(output_file.o): In function `gz_file_write':
output_file.c:(.text+0x738): undefined reference to `gzwrite'
./libsparse.a(output_file.o): In function `gz_file_pad':
output_file.c:(.text+0x7bf): undefined reference to `gztell64'
output_file.c:(.text+0x7eb): undefined reference to `gzseek64'

./libsparse.a(output_file.o): In function `gz_file_skip':
output_file.c:(.text+0x82e): undefined reference to `gzseek64'
./libsparse.a(output_file.o): In function `gz_file_open':
output_file.c:(.text+0x88c): undefined reference to `gzdopen'
collect2: error: ld returned 1 exit status
Makefile:58: recipe for target 'simg2img' failed

Most easy and ugly fix is putting -lz after $< $(LDFLAGS)

Commit 7442ceb should have fixed the issue. Let me know if that worked for you.
