Big endian in combined one-pass build

- Subject: Big endian in combined one-pass build
Hi all.
I am trying to compile GCC 4.5.1 and newlib-1.18.0 in one-pass
combined build. I created symlink to newlib directory in gcc
directory. Target is arm-elf.
I use configuration options --disable-multilib and --with-endian=big.
After compilation of toolchain, I can see that Newlib was compiled in
LE mode, so I can not compile my software properly.
I noticed that in order to compile newlib in BE mode, I have to force
GCC target to armeb-elf (and then newlib have to be patched, because
it does not recognize armeb target)
Questions are :
1) Why is this happening and how to force newlib to compile in BE mode ?
2) Can --with-endian=big flag work even if I disabled multilib (i.e.
is multilib necessary for BE mode build ?)
3) Do I always have to use armeb-elf instead of arm-elf target when
multilib is disabled
Thanks for the answers,
Drasko
