  I don't know.  It seems like a sensible enough place for it at first
glance.

  Or if you want to be really flexible about it, grep out the full path and
test if the files exist in that path....

gcc_install_dir="`gcc -print-search-dirs | grep install | cut -d ' ' -f 2`"
predep_objects="`ls -1 ${gcc_install_dir}crtbegin.o 2>/dev/null`"
postdep_objects="`ls -1 ${gcc_install_dir}crtend.o 2>/dev/null`"


    cheers,
