std::random_device in libstdc++ reads RDSEED on x86 Linux. On an AMD
EPYC 9V45 (Zen 5) CI runner its 32-bit results repeat about 130 times
in 65536 draws, so guest_posix_random fails. libc now exports
HostEntropy_nid_no_patch, which uses getentropy (rand_s on Windows) and
throws when the OS cannot provide entropy. arc4random, arc4random_buf,
sceRandomGetRandomNumber, /dev/random and /dev/urandom reads,
std::_Random_device and sceKernelUuidCreate use it, and the arc4random
and random device TechnicalDebt entries say so.

Every library CMakeLists.txt ended with the same block removing -static,
-static-libgcc and -static-libstdc++ from CMAKE_EXE_LINKER_FLAGS on MinGW,
because core/libs/CMakeLists.txt only removed them after adding the library
directories. Remove them before the libc and library directories are added
so each directory inherits the stripped flags, and drop the 52 copies.

Fill the buffer from std::random_device and reject a null buffer or a
size above SCE_RANDOM_MAX_SIZE (64) with SCE_RANDOM_ERROR_INVALID, as
the system library does.
