ls: fix output of dangling symlinks colored as target

This is related to commit b7f2b51c, 2010-01-01,
"ls: fix color of broken symlinks colored as target"
which didn't handle the --dereference case.
The simplest way to reproduce the resultant
erroneous "argetm" is as follows:

 $ ln -s /no-such dangle
 $ env LS_COLORS=ln=target ls --dereference --color
 ls: cannot access dangle: No such file or directory

sort: avoid a NaN-induced infloop

These commands would fail to terminate:
    yes -- -nan | head -156903 | sort -g > /dev/null
    echo nan > F; sort -m -g F F
That can happen with any strtold implementation that includes
uninitialized data in its return value.  The problem arises in the
mergefps function when bubble-sorting the two or more lines, each
from one of the input streams being merged: compare(a,b) returns 64,
yet compare(b,a) also returns a positive value.  With a broken
comparison function like that, the bubble sort never terminates.
Why do the long-double bit strings corresponding to two identical
"nan" strings not compare equal?  Because some parts of the result
are uninitialized and thus depend on the state of the stack.
