New pthread_cond_t and hppa.

[Carlos O'Donell]

Torvald,

On hppa we had no free word to use for the newer expanded
pthread_cond_t. Since the first four words of pthread_cond_t
are going to be "1, 1, 1, 1" in legacy applications it looks
like I need to reserve at least one of these lowest bit values
for the initializer I use to decide if the old-style structure
has been converted or not.

What's your take on shaving 1-bit off of __wseq32 or __g1_start32?
