So, there's a problem for OpenSSH build with spec'ing LD=/usr/bin/ld ?


in this particular case, apparently yes.  not generally, though.

ok

What's *intended* re: openssh?  Support for LD=ld or only =gcc, or undef'd ?


Well the intent is you should be able to set CC and LD to whatever you
want as long as they work.  In this case, the OSSH_CHECK_LDFLAG_LINK
test invokes autoconf's AC_LINK_IFELSE with uses CC not LD.  I'm not
sure what to do about it yet though.


cmake! ;-)
