This code probably won't work when cross-compiling, because it mixes
host platform and target tools.
If you use the new 'ldd' module, it
- should work also when cross-compiling,
- should be immune to changed addresses in the output of 'chatr',
'dump -H', 'elfdump -Dl', 'ldd', 'odump -Dl',
- simply feels safer to use the appropriate command for each system,
rather than trying "chatr" or "odump" on every system.
To use the 'ldd' module is simple:
- add an AC_REQUIRE([gl_LDD]),
- use
$LDDPROG conftest$ac_exeext $LDDPOSTPROC
instead of
($gl_ldd conftest$ac_exeext) 2>/dev/null
