  Fix -gz=zlib options for linker

gcc translates -gz=zlib to --compress-debug-options=zlib for both assembler and linker
but clang only does this for assembler.

The linker needs --compress-debug-options=zlib option to compress the debug sections
in the generated executable or shared library.

Due to this bug, -gz=zlib has no effect on the generated executable or shared library.

This patch fixes that.
