This libgo patch by Than McIntosh adds a few more explicit references
to enumeration constants (RUSAGE_SELF, DT_UNKNOWN) in sysinfo.c to
insure that their hosting enums are emitted into DWARF, when using a
clang host compiler during the gollvm build.  Bootstrapped and ran Go
testsuite on x86_64-pc-linux-gnu.  Committed to mainline.
