Here's how the compiler was configured and compiled:
$ tar -xjvf gcc-core-3.4.0.tar.bz2
$ cd gcc-3.4.0
$ ./configure --prefix=/usr/local/armdev --target=arm-elf --with-newlib --enable-languages=c
The following lines were uncommented in gcc/config/arm/t-arm-elf:
MULTILIB_OPTIONS += mno-thumb-interwork/mthumb-interwork
MULTILIB_DIRNAMES += normal interwork
MULTILIB_EXCEPTIONS += *mapcs-26/*mthumb-interwork*
$ make
$ sudo make install
In case it matters, I'm currently using binutils-2.15.
