make check-tcg fails on Fedora with:
vtimer.c:9:10: fatal error: inttypes.h: No such file or directory
Fedora has a minimal aarch64 cross-compiler, which satisfies the
configure checks, so it's chosen instead of the dockerized one.
There is no cross-version of inttypes.h, however.
Fix by using stdint.h instead. The test does not require anything
from inttypes.h anyway.
