[ECOS] 2.0b1/eCosCentric ARM tools little-endian only?

[Grant Edwards <grante at visi dot com>]

I downloaded and installed eCos 2.0b1 for arm-elf using the
download/install tool from the web page.  I've built eCos libs
for my target (which is big-endian).  IOW, the following works
fine:

  $ ecosconfig new <target>
  $ ecosconfig tree
  $ make

However, when I try to build tests the link fails because the
toolchain from eCosCentric only supports little-endian (AFAICT):

  $ make tests
  [...]
  make -r -C hal/common/v2_0b1 tests
  make[1]: Entering directory `/home/grante/ecos/hal/common/v2_0b1'
  arm-elf-gcc -mcpu=arm7tdmi -mbig-endian -g -nostdlib -Wl,--gc-sections -Wl,-static -L/home/grante/ecos/install/lib -Ttarget.ld -o /home/grante/ecos/install/tests/hal/common/v2_0b1/tests/context tests/context.o
  /opt/ecos/gnutools/arm-elf/bin/../lib/gcc-lib/arm-elf/3.2.1/../../../../arm-elf/bin/ld: /opt/ecos/gnutools/arm-elf/bin/../lib/gcc-lib/arm-elf/3.2.1/libgcc.a(_udivsi3.o): compiled for a little endian system and target is big endian
  File in wrong format: failed to merge target specific data of file /opt/ecos/gnutools/arm-elf/bin/../lib/gcc-lib/arm-elf/3.2.1/libgcc.a(_udivsi3.o)

Was this a conscious decision?

Has anybody been able to build an app for a big-endian ARM
platform using this toolchain?

Are there any other big-endian ARM targets I can try building?

The compiler version is 3.2.1:

  $ arm-elf-gcc --version
  arm-elf-gcc (GCC) 3.2.1 (eCosCentric)

Why does gcc pick the wrong libgcc.a even though it was told
-mbig-endian?
