trace.c: do not mark getnanotime() as "inline"
trace.c: do not mark getnanotime() as "inline"

Oracle Studio compilers don't allow for static variables in
functions that are defined to be inline. GNU C does permit this.

Let's reference the C99 standard though, which doesn't allow for
inline functions to contain modifiable static variables.
