Newer architectures have no chown syscall, so use fchown* syscalls for testing printuid. * tests/uid.test: Use fchown instead of chown. * tests/uid.c: Test __NR_fchown instead of __NR_chown. (main): Use __NR_fchown instead of __NR_chown. * tests/uid32.c: Test __NR_fchown32 instead of __NR_chown32. (main): Use __NR_fchown32 instead of __NR_chown32. * tests/uid16.c: Test __NR_fchown and __NR_fchown32 instead of __NR_chown and __NR_chown32. (main): Use __NR_fchown instead of __NR_chown. * tests/uid.awk: Update regexp.
