scons: Fix libelf linking errors when using clang/llvm
This patch fixes a linking error that occurs when using clang/llvm in
combination with older versions of glibc. The fix involves adding
-std=gnu89 to the command line when compiling libelf as clang defaults
to c99, causing issues with the symbols in sysmacros.h being defined
multiple times.
