Yes. The "install" target generates the script using shell
redirection:

	-sed -e "s#^GISBASE.*#GISBASE=${INST_DIR}#" ${ARCH_BINDIR}/grass${VERSION_MAJOR}${VERSION_MINOR} > ${BINDIR}/grass${VERSION_MAJOR}${VERSION_MINOR}

This will overwrite any existing target.

[Developers: the correct fix is to create a temporary file and then
install it using the INSTALL variable which is set by autoconf's
AC_PROG_INSTALL macro. That will be the path to the "install" program
if it is found, or the "install-sh" script otherwise. Both of these
would have replaced the symlink with the new script rather than
overwriting the symlink's target.]

It will have been updated. It's a script, so you can see what it
contains. It just sets GISBASE then executes Init.sh.
