Except that the shared libgcc installation uses, or did use, the 
definition in the subdirectory Makefile - not through design to avoid an 
unsafe shell script using programs that might be linked against libgcc, 
but rather through fragile implementation accident because of stage 
submakes not getting the toplevel definition of INSTALL passed down.
