[Mono-dev] Compilation error for ARM

[Rodrigo Kumpera]

Hi,

The functions that uses shm_* exists for making performance counters
readable from the outside.
But the patch to export performance counters has not yet hit trunk so, for
now, you can just comment the offending
code.

It would be nice, thou, to have a configure option to turn this off once it
hits trunk as embedded targets (as yours) might not
have proper support.
