support). If the bug is caused by binutils then consider it a head's up. If something in my toolchain is broken because it was compiled with unsupported gcc, consider it a head's up.
Did you try to rebuild libtool ?
Right in one! Please close as invalid, my libtool was apparently broken. after rebuilding libtool, apr builds just fine with either compiler.
