This patch fixes the build of libpthread for MIPS.  The definition of
_test_and_set uses __THROW after the prototype: but attributes are only
accepted after the prototype in function declarations which aren't
definitions, not between the prototype and the function body in a
definition.  The proper macro to use here is __NTH (placing the attribute
before the prototype).

glibc does the same thing, so this is also a sync up with glibc
