Identical code folding folds identical functions into a single copy, saving disk space. Generally useful for large C++ applications.
Only the gold linker can handle icf when using the gcc toolchain, although icf is generally superior when using llvm/lld.
Also add support for function-sections, this is recommended for use with ICF when using gcc/gold but not strictly necessary.
icf-all is not recommended for gcc/gold but is left as an option. icf-all is generally safe for clang/lld due to -faddrsig being default in clang.
Additionally, fix a thinko where runpath wasn't being filtered from cflags/cxxflags.
