System emulation tests do not run in a hosted environment, since they
do not link with libc. They should only use freestanding headers
(float.h, limits.h, stdarg.h, stddef.h, stdbool.h, stdint.h,
stdalign.h, stdnoreturn.h) and should be compiled with -ffreestanding
in order to use the compiler implementation of those headers
rather than the one in libc.
Some tests are using inttypes.h instead of stdint.h, so fix that.

We don't run this during check-tcg as we would need to check stuff is
echoed back. However we can still build the binary so people can test
it manually.
