odd build failure on trunk, i686-pc-linux-gnu

[Phil Edwards]

Holy cow, I don't understand this one at /all/.  When calling xgcc to create
the shared libstdc++, collect2 is trying to grab both /usr/lib/crti.o and
crtbegin.S more than once, producing the following amusing and discouraging
errors (expanded via -v).  It's using current CVS gcc unified with current
CVS binutils.

What causes these files to be multiply listed, i.e., where do I look?
