commit: https://git.buildroot.net/buildroot/commit/?id=4a1bcbe17e83c78de31a4cdf9161c1342d1021ae
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Run script with 'errexit' bash option to detect any errors from
subcommands.

It will fix situation where 'ddr_fw.bin' was missing but successfull
build created broken boot image. Post image script report this by:

cat: /home/user/buildroot/output/images/ddr_fw.bin: No such file or directory

and build finish with success.
