build: define getcallerpc in u.h (fix for Plan 9 build)
. By defining getcallerpc(x) as __builtin_return_address(0)
here, it becomes possible to use the Plan 9 compatible form
when compiling using GCC. The alternative is to add conditional
compilation based on the compiler identity in "cmd/8g/gsubr.c"
to distinguish between the two cases.
