  The test is not a run-time check, so update the description.
Also use readelf -W for a more stable output format.

This avoids garbled configure messages:

checking for s390-specific static PIE requirements (runtime check)...  0x0000000000000017 (JMPREL)             0x280
yes

---
v2: Capture the grep output instead of using grep -q.

The typo I pointed out remains (LC_ALL vs LC_ACLL).
