The attached patched fixes the usage of MPX in presence of
"-Wl,-as-needed" option. 'make checked' on MPX-enabled machine.
"--push-state" and "--pop-state" are not supported by gold at the
moment. But that's OK because using MPX with gold only recommended in
static build.
Would that be OK for trunk?
