  Libgcc2 is a target library; it is being compiled by the cross compiler
at this stage of the make process, so the error message comes from the
modified version of the compiler that you have created.  That means it is 
most likely a bug in the changes you made, probably the ones to combine.c,
such that it is now combining insns in some invalid fashion, thereby
generating invalid rtl that copy_rtx detects and complains about.
