grep >/dev/null instead of grep -q

[Karl Berry]

Hi Ben,

For your consideration ...

grep -q is not supported on the sadly-still-widely-used Solaris 5.10.  I
realize that at least some, maybe all, of these tests only execute on
other systems, but it somehow seems simpler and more readable to just
always redirect to /dev/null instead of worrying about whether it is
necessary.

Oh, and may as well quote the periods in ld.so.1, just in case ...
