When compiling on Suse11:
linux-user/syscall.o: In function `do_syscall':
/work/linux-user/syscall.c:8090: undefined reference to `syncfs'
library support was added to glibc in version 2.14, which newer than
the glibc in the oldest distros qemu building is still supported (2.11
in Sles11).
CONFIG_SYNCFS checki and guard needed.
