Firstly, I wanted to say thanks for looking at this, there are some
really great fixes in here.

It failed in automated testing as glibc-utils is glibc specific and
musl builds couldn't cope with that.

We can certainly do:

RDEPENDS_${PN}-ptest_append_libc-glibc = " glibc-utils"

but I'm not sure what that would mean for lttng on musl or if lttng
ptest on musl even makes sense.

I'm travelling so haven't been able to dig any further so sorry for
being terse but just wanted to give a heads up on this.

Autobuilder failure:
