ldd: make try_trace more robust and portable
It was noted in 2005 (BZ #832), 2006 (BZ #3266), and 2007 [1] that ldd fails on shells other than Bash >= 3.0 because of the pipefail option around try_trace (added on 2004-12-08). EGLIBC was patched in 2008 [2] (r6912) to make the pipefail check run only on shells that support it, but RTLD output would still be lost on other shells with certain SELinux policies. This patch rewrites try_trace to work on any POSIX-conformant shell in such a way as to also work with such SELinux policies. It also obviates one difference between glibc and EGLIBC.

McDermott <pj@pehjota.net> [BZ #832] * elf/ldd.bash.in (try_trace): More robustly and portably work around SELinux terminal write permissions by using a command substitution instead of a pipeline and pipefail option.
