I had to add "--disable-spinlocks" to build PostgreSQL 8.4.7 for AArch64.

Did not checked other versions.

"--disable-spinlocks" is merged into upstream OE. Once we get patch to add spinlocks support I will change status and merge patch.

We still need proper port for this for maximum performance of postgresql.

Also, the arm version in s_lock.h uses swpb which is depreated in armv6+. This should also be fixed for LEG.

Postgressql 9.3 is using __sync_lock_test_and_set, so this is fixed upstream already.
