fix compile with DODEBUG=y
Since more projects using two-stage cross-compile process we cannot add libgcc_eh.a unconditionally. We must check if a real file is referenced by the cross-compiler. Toolchains with --disabel-shared build have a single libgcc.a containing all required symbols. Tested with a debug build for x86.
