[Buildroot] [PATCH 5/6] linux/perf: build in a sub-directory

[Yann E. MORIN]

Currently, we only build perf for the target.

However, analysing some of the results gathered by perf (aka trace) may
require running perf (aka trace) on the host, so we'll have to build
perf for the host too.

To avoid mixing target and host binaries, we need to build them in
separate directories.

This commit only moves the target build, in preparation of the host
build to come later.
