scripts: fix catching failures

POSIX 1003.1-2008 does not say whether "set -e" should catch a sub-shell
that exits with !0 (it has a list of conditions to catch, but no list of
conditions not to catch, and this situation is not listed).

bash-3 does not catch such a failure, but bash-4 does. That why, on my
Squeeze system I did not see the issue, while Thomas did on is Lenny chroot.

     3 reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g., MPC8548,
     4 MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.6.0,
     5 for e500v2 DPFP support) and will generate appropriate dual-precision
     6 floating point instructions by default.

     8 Note: If building a Linux kernel with this toolchain, you will want to make
     9 sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions
    10 from getting into the kernel (which is currently unsupported). At this time,
    11 the kernel build system properly passes those two options, but older kernels
    12 were only passing -mno-spe by default."
