Description
drreg-test subtest 8 fails on Travis w/ following error:
Config:

To reproduce, uncomment in drreg-test.c. Not reproducible locally for me, only on Travis.
Contributor guide
Research direction
Start with subtest 8 in drreg-test.c and reproduce it using the Travis configuration shown, including the uncommented test. Trace the rip-relative re-relativization failure reported by the test and compare the Travis-only behavior with a local run. Done means the subtest no longer reports the unreachable-target encoding error in the stated configuration.
