Subject: [PATCH] Fix build failure of lld/ELF/OutputSections.cpp

On Windows when zlib is enabled, zlib header introduced some
Windows headers which defines max as a macro. Since OutputSections.cpp
uses std::max with template argument, this causes compilation
error.

Define NOMINMAX before include zlib header to avoid introducing
max as a macro.
