Adrian Bunk 56da8174e7 json-c: Don't --enable-rdrand
In recent years AMD CPUs have had various problems with RDRAND
giving either non-random data or no result at all, which is
problematic if either build or target machine has a CPU with
this problem.

The fallback is /dev/urandom, and I'd trust the kernel here.

--enable-rdrand was added in an upgrade to a new upstream
version without mentioning any reason.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
