Enable creation of static userspace probes in incremental builds.
To define USDT probes, dtrace -G makes use of relocations for undefined symbols: the target address is overwritten with NOPs and the location is recorded in the DOF section of the output object file. To avoid link errors, the original relocation is destroyed. However, this means that the same input object file cannot be processed multiple times, as happens during incremental rebuilds. Instead, only set the relocation type to NONE, so that all information required to reconstruct USDT probes is preserved. Reported by: bdrewery MFC after: 3 weeks Sponsored by: The FreeBSD Foundation
