[OE-core] [PATCH] db: disable the ARM assembler mutex code

[Li Zhou]

The swpb in macro MUTEX_SET will cause "undefined instruction" error
on the new arm arches which don't support this assembly instruction
any more. If use ldrex/strex to replace swpb, the old arm arches don't
support them. So to avoid this issue, just disable the ARM assembler
mutex code, and use the default pthreads mutex.
