Subject: [PATCH] app-shells/bash: mark as LTO-unsafe in particularly old
 versions

Due to implicit function declarations, LTO fails to detect the
availability of a function and errors out due to an undefined reference
at link time.

It's fixed in bash 4.0 and on, but the value of backporting the fix to
versions of bash that have niche use (people interested in exploring old
versions, not people who are looking for the shebang interpreter for
their system scripts) is a matter of some question...
