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.
