cross-compiling

Since libgcc.a won't be used for *building* gcc (unless build!=host),
then yes, that is ok. I don't know what you mean by "empty", though -
if it does not have any functions, but the target relies on functions
in it, then the cross-compiler won't work (specifically, binaries
compiled with it won't link).
