There was a reason why I chose that particular search order.  Consider
the most common case, where someone invokes ld without giving a -T
or -dT option.  If your copy of ld supports built-in scripts then for
the default target you'll always use one of the built-in scripts.  If
ld doesn't support built-in scripts, then ld reads the script from
ldscripts/, which is usually installed in $prefix/lib/.  Your change
could make ld choose some ldscripts/ other than the one installed
along with the ld binary.  For instance, if I build and install a new
version of ld using a prefix of /usr/local, then I always want to use
scripts in /usr/local/lib/ldscripts/.  I wouldn't want to pick up the
old system scripts in /usr/lib/ldscripts/ if -L /usr/lib happened to
be passed to ld!
