Such approach suffers the same problem as the {nss,nspr}-config
scripts: you need to use pkg-config data from both NSS *and* NSPR in
order to get all the needed header files' paths.

So, it won't bring any added benefit, at the expense of increased
complexity: not advisable as a first choice in my opinion, perhaps only
as a fall-back choice if {nss,nspr}-config scripts are not available on
the system...
