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.
