Why a different debug build? Whats the difference? And what I should be looking 
for? {in the debug build?}

Wrt 464687 - the only issue i see is the false error check - [the
patch I sent in the previous e-mail should fix this check.]

The other minor issues are:

The CFLAGS are getting used once in <seq> - twice in <openmp> and
three times in <mpich> builds.  Perhaps the FLAGS cleanup didn't fix
all the builds.. [I won't cause problems - just make it a bit more
unreadable..]

And you appear to remove
-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 form everywhere
[including CC,CXX,LD] - the buggy behavior was with gfortran
only.. You might want to remove it from FFLAGS - but keep it with
others...

Perhaps the 'gofrtran -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1'
behavior on i386 is a gfortran bug?
