[OE-core] [PATCH] distro/defaultsetup.conf: Append TCLIBC to TMPDIR by default

[Koen Kooi]

From: Richard Purdie <richard.purdie at linuxfoundation.org>

The current solutions to share uclibc, eglibc and glibc builds in the
same tree all have various issues associated with them. Appending the
suffix to TMPDIR seems like the best solution since sstate (which
defaults to outside TMPDIR) will allow reuse of any components.

This avoids messy changes to the core with other approaches to this
problem inevitably entail, usually in code where this abstraction isn;'t
logically best placed.
