libreadlne: create symlinks for .so
Currently, libreadline only installs
```
/usr/lib/libhistory.so.8 -> libhistory.so.8.2
/usr/lib/libhistory.so.8.2
/usr/lib/libreadline.so.8 -> libreadline.so.8.2
/usr/lib/libreadline.so.8.2
```
But there is no `libreadline.so` or `libhistory.so` available.
So this happens:
```
root@OpenWRT:~# cat a.c
int main() {
}
root@OpenWRT:~# gcc a.c -lreadline
/usr/bin/ld: cannot find -lreadline: No such file or directory
collect2: error: ld returned 1 exit status
```
Unless, of course, one uses `-l:libreadline.so.8`... But that
doesn't help with binaries that try to dynamically open
`libreadline.so`. I have one of those here (the STklos Scheme
compiler -- I didn't make a PR for it because it's far from
being ready, but one issue is that it does use dlopen to use
readline...)
With the symlink, it works:
```
root@OpenWRT:~# ln -s /usr/lib/libreadline.so.8 /usr/lib/libreadline.so
root@OpenWRT:~#
root@OpenWRT:~# gcc a.c -lreadline
root@OpenWRT:~#
```
Another example: when trying to package rlwrap, the build failed
complaining it could not find readline (using `-lreadline`).
It would then be necessary to change rlwrap's `configure.ac`
(and also in all packages that use readline), but it seems
simpler to add the symlinks...
This PR changes the Makefile so it will include the links.
