Recent nss upgrade breaks ssl support in curl in a CentOS 6.7 build

Hi all,

I found recent upgrading nss cause curl configure failing to detect nss 
availability.
Happens only in CentOS 6.7, didn't observe it on Ubuntu 14.04.

nss upgrade is present both in master and in libreoffice-5-1.

In libreoffice-5-1 the commit where this is first seen is:
<https://gerrit.libreoffice.org/gitweb?p=core.git;a=commitdiff;h=ecdb54d5f129c96c06feda32915f249d01254e18>

Relevant verbose configure in CentOS follows (obtained on CentOS 6.7 
compiling libreoffice5-1 branch):
"

only)... no
