Remove patch files.

We haven't maintained these, so it's misleading to have a subset. I've
kept the one actual _sysroot_ patch though, mainly out of ignorance :-)

-This patch is one of the motivating reasons for upgrading glibc from 2.15.

-Unfortunately, we couldn't upgrade to 2.19(*) due to some users having 2.17.

-* - which no longer needs the patch, since the #ifdefs around __gnu_inline__ are
-    worded so that compilers that don't have __GNUC_PREREQ(4, 3) can still get
