elfutils import and debuginfo

[Stan Cox]

This "patch" gets this test, which is testing frysk handling of external
debuginfo, to pass:
./TestRunner frysk.hpd.TestSysRoot
 Running testHaveSysRoot(frysk.hpd.TestSysRoot) ...PASS
 OK (1 test)

The test artificially creates a chroot by
creating /usr/bin, /usr/lib/debug, etc under a test directory and
populating that by using cp, debugedit and ed-strip.  With elfutils
0.133 the test hits the case SHT_DYNSYM and ends up returning
DWFL_E_NOERROR.  With elfutils  0.129 DWFL_E_NO_SYMTAB would be returned
resulting in find_debuginfo being called to find the debuginfo.
