Subject[PATCH] perf: Fix libdw-dev package name in error message
Date
The headers required for DWARF support are provided by the libdw-dev
package in Debian-based distros. This patch corrects the elfutils-dev
package name to libdw-dev in the Makefile error message when libdw.h is
not found.

I don't think any distro has an elfutils-dev package but the name was chosen because of the usual RedHat/Debian -devel/-dev convention.
