Re: [PATCH v2 10/10] Tilera (and Linux asm-generic) support for glibc

[Chris Metcalf <cmetcalf at tilera dot com>]

This change didn't rouse any discussion when I posted it the first time,
but it is required to be able to build the tile architecture libc properly,
due to the relatively novel use of "GLIBC_2.12 GLIBC_2.15" in the
shlib-versions file.  Ping?
