linux-user: SPARC "rd %tick" can be used by user application
we have the same problem decribed in 7d6b1daedd
("linux-user, ppc: mftbl can be used by user application")
for ppc in the case of sparc.
When we use an application trying to resolve a name, it hangs in
0x00000000ff5dd40c: rd %tick, %o5
0x00000000ff5dd410: srlx %o5, 0x20, %o4
0x00000000ff5dd414: btst %o5, %g4
0x00000000ff5dd418: be %icc, 0xff5dd40c
because %tick is staying at 0.
As QEMU_CLOCK_VIRTUAL is not available in linux-user mode,
simply use cpu_get_host_ticks() instead.
