libnspr: fix build with the musl C library 

Even though libnspr uses a configure script, it does look at __GLIBC__
and other macros to determine whether certain C library features are
available or not. Such things fails completely with the musl C
library, since it doesn't define __GLIBC__.

To fix this, we borrow some logic from Alpine Linux, which consists in
explicitly specifying which features are available in the musl C
library.

Fixes:
