libnspr: fix link error with musl toolchains

Browse source 
When linking against libnspr with musl toolchains we get undefined
references to `getprotobyname_r' and `getprotobynumber_r', for example
when compiling libnss:

/home/test/autobuild/instance-1/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/lib/libnspr4.so:
undefined reference to `getprotobyname_r'
/home/test/autobuild/instance-1/output/host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/lib/libnspr4.so:
undefined reference to `getprotobynumber_r'

That's because musl does not have an implementation of these functions,
so we need to enable their internal implementation from libnspr.

This patch was backported from Alpine Linux commit
a162da839db0d3f8be94a5c1ad2e2e54e691c38a.
