I reverted this $(CC)-$(CROSS_COMPILE)gcc-conversion patch and built
with M54455EVB_config and CodeSourcery's freescale-coldfire-4.2-125-
m68k-uclinux-i686-pc-linux-gnu.tar.bz2. But couldn't reproduce.

As already Wolfgang pointed out, `gcc -print-libgcc-file-name' of your
toolchain seems weird. This might be buildroot problem?

(1) Please show us the '-print-libgcc-file-name' part with your patch
    applied:

    $(CC) $(CFLAGS) -print-libgcc-file-name
    ---------------------------------------

    (without patch)
        /opt/freescale/usr/local/gcc-4.2.47-uclibc-0.9.47/
        m68k-uclinux/lib/gcc/m68k-uclinux/4.2.1/m5407/msep-data

    (with patch)
        /* we'd like to confirm this one */

(2) Could you try other toolchains, such as this one[1], in order to
    sort this out?
