Honor LDFLAGS when building pdl.

[0-wiz-0]

This is needed e.g. when building with RELRO support.

Coverage remained the same at 52.615% when pulling e48b200 on 0-wiz-0:master into 1d62636 on PDLPorters:master.

Thanks for this! Can you confirm the ordering is right, ie that the LDFLAGS doesn't go at the end? I've restarted the one CI job that failed, since it's just showing a timeout which is vastly unlikely to be your fault!

[0-wiz-0]

I've used it for -Wl,-z options and it worked fine where it was.

Looks good to me. @devel-chm want to merge?

Since the above checks do not show the passing AppVeyor build (probably a notification hiccup), here it is: https://ci.appveyor.com/project/zmughal/pdl/build/1.0.627.

This seems reasonable.

Merge: Aye.

@0-wiz-0 Thanks very much for this! Going forwards, it will be better if you do it on a local branch that's not master, which makes rebasing a bit less complicated should it be needed :-)
