ld not sucking in /usr/lib/crt1.o - or is it me?

Howdy,

I installed 5.1 on my laptop, then synced up to -current as of
8 hours ago. I'm trying to build the 1.5 branch of Firebird
(the DBMS), but run into the following error:

ld  ../temp/static.gpre/gpre/cmd.o ../temp/static.gpre/gpre/cme.o

If I add /usr/lib/crt1.o to the file list it works OK.  Any reason
why ld isn't pulling this in automatically?  Feel free to correct
me if I'm missing the obvious and if there's a better way of
resolving this.  Thanks.
