Subject: dev-util/strace: Add use flag for elfutils.
X-Git-Url: http://git.tremily.us/gitweb.cgi?a=commitdiff_plain;h=11c6d80669d85985bb9f8aabd052c89a34a2c84f;p=gentoo.git

dev-util/strace: Add use flag for elfutils.

strace can use libdw to implement stack tracing support and will use it
automatically if it is installed on the system. The commit makes this
configurable.

Closes: https://github.com/gentoo/gentoo/pull/8860
