It seems to me that what we really need to have available is the header 
'tm.h',
which is present in build-dir/gcc. It includes all the target dependent 
config
files and finally defaults.h.  At the end both WORDS_BIG_ENDIAN and, in 
case,
FLOAT_WORDS_BIG_ENDIAN have the correct values.
The latter seems meaningful only for 'arm', 'c4x' and 'mmix'. Also, 
'arm' seems
particularly tricky (and currently v3 works well there, so... ;)

but I don't know if in practice we have to do something special or not, 
I hope
not...
