Build OmpSs-2 llvm with zlib

Browse Source 
The zlib is required by the lld linker to work with zlib compressed
sections in the ELF header. We also set the LD_LIBRARY_PATH during the
build, as otherwise the llvm-tblgen binary is unable to find the zlib
library, as its missing the directory in the rpath.
