Revert the ld --as-needed patch. This breaks Fedora Core 3, due to a strange

interaction between ld, readline, termcap, and psql. The symptom is psql
failing with this error on startup:

    symbol lookup error: /usr/lib64/libreadline.so.4: undefined symbol: BC

I'm still trying to find the best way to solve this, but in the mean time
I'm reverting the patch in order to unbreak FC3.
