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`"
