Yann E. MORIN" 4b173045e9 libc/glibc: add 2.10.1
Woo... It seems the glibc guys finally decided that tarballs
were not deprecated, in fact.

The patchset was vampirised from Gentoo (kudos, guys!), and
applies to glibc+ports, so that's why it's been added as a
patchset against ports, not against glibc.

ripped from Debian
the R10000 needs an LL/SC Workaround. If not applied all R10k before
rev 3.0 misbehave on atomic ops and rev 2.6 and lower (e.g. SGI IP28)
die after very few seconds with a deadlock due to even more erratas.
