Without this, pkgsStatic.pkgsLLVM.hello fails with segfaulting binaries because of the issue described at [0]. In summary, llvm's linker has a different behaviour to GCC's when supplied with both -static and -Wl,-dynamic-linker=...; GCC copes with it, but LLVM produces a binary which segfaults on startup. It appears to be necessary to omit the dynamic linker in this case. nixpkgs' static adaptor passes -static via NIX_CFLAGS_LINK which was not accounted for prior to this commit in the checkLinkType logic. For good measure I put the other NIX_ flags affecting link in the same logic. Additionally, $NIX_CFLAGS_LINK_@suffixSalt@ is not available until later than it was originally set, so set $linkType close to its point of use. I checked for earlier uses by studying the shell trace output and couldn't find any.
