From: Khem Raj <raj.khem at gmail.com>
When using distros which use old kernels gnutls fails to build
due to missing SYS_getrandom, therefore we need to check for this
before using it.
Fixes errorr e.g.
| ../../../gnutls-3.5.3/lib/nettle/rnd-linux.c: In function 'have_getrandom':
| ../../../gnutls-3.5.3/lib/nettle/rnd-linux.c:59:42: error: 'SYS_getrandom' undeclared (first use in this function)
| # define getrandom(dst,s,flags) syscall(SYS_getrandom, (void*)dst, (size_t)s, (unsigned int)flags)

+Subject: [PATCH] rnd-linux: added check for SYS_getrandom being defined
+
+This allows to compile the getrandom() code in old Linux systems
+which do not have the system call defined.
