See above issue.
--------------------------------
+Symptoms:
+ On x86_64 hosts with 32bit userspace the GMP build fails with:
+ configure: error: Oops, mp_limb_t is 32 bits, but the assembler code
+ in this configuration expects 64 bits.
+ You appear to have set $CFLAGS, perhaps you also need to tell GMP the
+ intended ABI, see "ABI and ISA" in the manual.
+
+Explanations:
+ "uname -m" detects x86_64 but the build host is really x86.
+
+Status:
+ CURRENT
+
+Fix:
+ None so far. See above issue.
+
+Workaround:
+ use "setarch i686 ct-ng build"
+
