Right.  I remembered all this.  BTW, this is *majorly stupid* behavior
for BSD/OS's linker.  You should complain to them that this behavior loses.

I'd really prefer to avoid this since we have mechanisms to handle these
kinds of issues via spec files.  Another option is for the tm.h file to
define REAL_LD_FILENAME.  But I don't recommend that either if we can use
specs to DTRT.

Why doesn't defining LINK_SPEC to add -L/shlib work?  Other ports do similar
things to override the location where things like libm is found (the PA
for example adds -L/lib/pa1.1 so that it picks up a PA1.1 specific version of
the math library).

Even if you had a "more stable compiler", what happens when you do an upgrade
of the entire system every few years -- and possibly the compiler has been
updated.

Really, it's a bad idea, even when the compiler only changes once every few
years.
