Did some research and my assumption was correct, the code
just created a new reference but not a copy.

So the attached patch should hopefully fix the issues on the HP/UX 
machine in the build farm.

Can you have a look at it please and push it so we can see how the build 
farm reacts?

Thanks
Christian

Subject: [PATCH] waf:lib/replace fix iconv checks on HP/UX

we need to copy away the list of LDFLAGS
to be tried before modifying it instead of
just creating a new reference and then continuing
with a modified list while it should have been
reset back to the original value
