[ltt-dev] lttng-ust can't build on ppc?

[Cui, Dexuan]

Hi, I got the following build failure on ppc:

| make[2]: Entering directory 'ust-0.11/libust'
|   CC     libust_la-buffers.lo
| In file included from buffers.c:30:0:
| ../include/ust/clock.h: In function 'trace_clock_frequency':
| ../include/ust/clock.h:111:6: error: 'CLOCK_TRACE' undeclared (first use in this function)
| ../include/ust/clock.h:111:6: note: each undeclared identifier is reported only once for each function it appears in
| ../include/ust/clock.h:112:17: error: 'CLOCK_TRACE_FREQ' undeclared (first use in this function)
| ../include/ust/clock.h:113:13: error: dereferencing pointer to incomplete type
| make[2]: *** [libust_la-buffers.lo] Error 1
| make[2]: Leaving directory `ust-0.11/libust'

I think commit 9c6bb08180ab0a65bbf3d47247a9d36e257fa44a introduced this issue.

Can someboby please have a look?

Thanks,
