[m-rev.] fix for Tru64 (dec-alpha-osf*) cc problem

[Fergus Henderson]

Estimated hours taken: 1
Branches: main

Fix a bug reported by Michael Cameron <Michael.Cameron at general.monash.edu.au>,
where on dec-osf-alpha* we were invoking `gcc' to link shared libraries
without checking whether it had been installed.

configure.in:
	For dec-osf-alpha*, use `cc' to link shared libraries if `gcc'
	is not in the PATH.
