[ECOS] GCC 4.2.2

["paul pescitelli" <1kernelhacker at gmail dot com>]

I have been attempting to build an ARM tool chain using the docs from
the ecos site located at
http://www.ecos.sourceware.org/ecos/tools/linux-arm-elf.html

I am having issue with getting GCC 4.2.2 compiled using the following
configure and compile command sets.


Scenario #1)

Configure GCC, ensuring that the GNU Binary Utilities are at the head
of the PATH:

    PATH=/tools/H-i686-pc-linux-gnu/bin:$PATH ; export PATH    (for
sh, ksh and bash users)
    set path = ( /tools/H-i686-pc-linux-gnu/bin $path )        (for
csh and tcsh users)
    mkdir -p /tmp/build/gcc
    cd /tmp/build/gcc
    /src/gcc/gcc-2.95.2/configure --target=arm-elf \
      --prefix=/tools \
      --exec-prefix=/tools/H-i686-pc-linux-gnu \
      --with-gnu-as --with-gnu-ld --with-newlib \
      -v 2>&1 | tee configure.out


Build and install GCC:

    make -w all-gcc install-gcc LANGUAGES="c c++" 2>&1 | tee make.out

FAILS with the following:
make[3]: Entering directory `/tmp/build/gcc/gcc'
/tmp/build/gcc/./gcc/xgcc -B/tmp/build/gcc/./gcc/

make[1]: *** [stmp-multilib] Error 2
make[1]: Leaving directory `/tmp/build/gcc/gcc'
make: *** [all-gcc] Error 2
make: Leaving directory `/tmp/build/gcc'



It appears that the wrong "as" gets called, the contents of the file
/tmp/build/gcc/./gcc/as as called above are

#!/bin/sh
exec  "$@"

Is this a bug ?


Scenario #2)
If I eliminate the "--target=arm-elf" it compiles just fine.
