Drop redundant -lc from a number of rules in Makefile.shared. It's

perfectly safe [compiler driver adds it] and in some situation even
perfectly appropriate [mixing -pthread and -lc on FreeBSD can have
lethal effect on apps/openssl]. I'd say we should get rid of more,
but I remove those I can test myself...
