[Buildroot] [PATCH 3/3] package/eudev: fix install with BR2_ROOTFS_MERGED_BIN=y

[Thomas Perale]

In reply of:
> Eudev install creates a symlink from $(sbindir)/udevadm to
> $(bindir)/udevadm if sbindir and bindir are different [1].
> Unfortunately the check considers only the configured values as
> strings and does not resolve symlinks. This means that in a merged-bin
> setup with sbindir=/sbin (symlink to /usr/sbin, which is a symlink to
> /usr/bin) and bindir=/usr/bin the /usr/bin/udevadm binary gets
> overwritten with a link to itself.
> 
> Set sbindir according to the merge setup to avoid the problem, bindir
> defaults to /usr/bin in any case.
