libm is used in cutils.c, but the library was not specified
when linking some binaries, throwing the following error:
cutils.o: In function `strtosz_suffix_unit':
/home/royger/xen-clean/tools/qemu-xen-dir/cutils.c:354: undefined
reference to `__isnan'
/home/royger/xen-clean/tools/qemu-xen-dir/cutils.c:357: undefined
reference to `modf'
collect2: ld returned 1 exit status
According to modf man page [0], -lm should be used when linking.
librt is used in qemu-time.c, but again the library was not specified
at link time, throwing the following error:
/home/royger/xen-clean/tools/qemu-xen-dir/qemu-timer.c:597: undefined
reference to `timer_gettime'
/home/royger/xen-clean/tools/qemu-xen-dir/qemu-timer.c:610: undefined
reference to `timer_settime'
../qemu-timer.o: In function `dynticks_start_timer':
/home/royger/xen-clean/tools/qemu-xen-dir/qemu-timer.c:565: undefined
reference to `timer_create'
../qemu-timer.o: In function `dynticks_stop_timer':
/home/royger/xen-clean/tools/qemu-xen-dir/qemu-timer.c:583: undefined
reference to `timer_delete'
collect2: ld returned 1 exit status
According to timer_getttime man page [1], -lrt should be used when
linking.
