This target allows you to have git installed in one location,
and have symbolic links to all of the programs installed in
another location. For example, if git was installed to /opt/git
with
make prefix=/opt/git install
you can install symbolic links in /usr/local/bin with
make symlinkprefix=/usr/local prefix=/opt/git \
install-symlinks
This makes it reasonably easy to remove such a package, by doing
rm -rf /opt/git
and then removing stale links with
find /usr/local -xtype l -print0|xargs -0 rm
(be sure to first see whether you indeed get only stale links listed).
This works by copying the directory hierarchy of $prefix to
$symlinkprefix (not copying or descending to any directories of the
name git* matched case-insensitively), then linking all the rest.
