The checkin that added that had the comment

	Workaround for (at least) some RedHat platforms:
	Add -lresolv in case it's missing but required by the heimdal libs.

so there apparently *are* platforms where it's needed.

The problem is that the test just checks whether -lresolv is missing, 
not whether it's missing *and* required.

The test we'd probably have to do would be to link some program with the 
Heimdal library without -lresolv and, if that fails, add -lresolv.

See, for example, the tests in AC_ETHEREAL_UCDSNMP_CHECK that checks 
whether -lsnmp needs particular additional libraries.
