Summary

0001501: cross-compile bash does not support "set -o pipefail" or $PIPESTATUS builtin variable

Description

When building BASH (3.2 or 3.1 with latest patch) using buildroot & uClibc (tested uClibc 0.9.29,0.9.28.3) I'm unable to use PIPEFAIL or PIPESTATUS.

PIPESTATUS Description :

http://tldp.org/LDP/abs/html/internalvariables.html [^]

pipefail script example :

set -o pipefail
cat /tmp/anynotfound | tee -a /tmp/test

will always return 0 has exit code. with the pipefail mode, the exit code should be the last non zero exit code (in this example cat /tmp/anynotfound fail so it should return 1)

PIPESTATUS exmaple :

exit 1 | exit 2 | exit 3
echo ${PIPESTATUS[@]}

PIPESTATUS should return string "1 2 3" but always return "0"
