[OE-core] [PATCH 1/3] lttng: Enable on musl and riscv

[Jonathan Rajotte-Julien]

Hi Khem,

This looks good, still please take some moment to read this thread from musl
mailing list regarding lttng-ust usage of _SC_NPROCESSORS_CONF. For now I would
maintain the disabling of lttng-ust when musl is used. I should have CC'ed you,
I forgot.

The modification for riscv64 seems good to me. We do support lttng-* for
riscv64 [2] on debian.
