FS#3846 - ppp-multilink in build system cannot replace ppp, but can also not installed at the same time.

dreieck:

PACKAGE_ppp-multilink seems to provide the ppp-daemon with added multilink functionality. So it should be possible to select ppp-multilink instead of ppp. But in the configuration system the dependencies are not set that way.

If some package required ppp, it still cannot be unselected if ppp-multilink is selected (see attached screenshot), as it is with many other packages where there are alternatives for the same functionality. Furthermore, PACKAGE_ppp-multilink=y will produce a clash with PACKAGE_ppp=y when it comes to the install step, see [[/index.php?do=details&task_id=3845|Task #3845]].

ppp has as Selected by-dependencies:

Selected by [y]: - PACKAGE_modemmanager [=y] - PACKAGE_pppossh [=y] && (PACKAGE_dropbear [=y] || PACKAGE_openssh-client [=n]) Selected by [m]: - PACKAGE_openfortivpn [=m] - PACKAGE_sstp-client [=m] Selected by [n]: - MODULE_DEFAULT_ppp [=n] && TARGET_PER_DEVICE_ROOTFS [=n] && m && MODULES [=y] - PACKAGE_rp-pppoe-sniff [=n] && BROKEN [=n] - PACKAGE_pptpd [=n]

where PACKAGE_ppp-multilink has none at all.

As Selects-dependency, they both have (in different order, but same items):
Selects: PACKAGE_kmod-ppp [=y] && PACKAGE_libc [=y] && PACKAGE_librt [=y] && PACKAGE_libpthread [=y]

The URL above is wrong, it happened due to auto-prepending stuff to a relative URL, see [[https://bugs.openwrt.org/index.php?do=details&task_id=3848|Task #3848]].

The correct URL is [[https://bugs.openwrt.org/index.php?do=details&task_id=3845|this one]].

Also, the attached file got missing, maybe due to the thing described in [[https://bugs.openwrt.org/index.php?do=details&task_id=3847|Task #3847]]. I re-attach it here. Fot the resons described in [[https://bugs.openwrt.org/index.php?do=details&task_id=3847|Task #3847]] this task also has no tags.
