mips32/64: Add extra suppression for mips32/64.

After the thread is detached not all thread memory is freed. This memory (dtv-dynamic thread vector)
can be used by the main thread. There are two types of run-time handling of TLS.
Difference is in the position of memory. It can be either before the thread pointer or
after the thread pointer.
Taken form the document http://www.akkadia.org/drepper/tls.pdf:
"Variant I for the thread-local storage data structures were developed
as part of the IA-64 ABI. Being brand-new, compatibility was no issue. The thread
register for thread t is denoted by tpt. It points to a Thread Control Block (TCB) which
contains at offset zero a pointer to the dynamic thread vector dtvt for the thread.

Variant II has a similar structure. The only difference is that the thread pointer
points to a Thread Control Block of unspecified size and content. Somewhere the TCB
contains a pointer to the dynamic thread vector but it is not specified where. This is
under control of the run-time environment and the pointer must not be assumed to be
directly accessible; compilers are not allowed to emit code which directly access the
dtvt."

Because of this we have two types of error when the program ends:
possibly lost, and definitely lost.
