Subject: eglibc: Upgrade from 2.18 -> 2.19

License formatting and address for FSF in the COPYING and COPYING.LIB
has changed.

Dropped patched already upstream and patches that were workarounds for
older glibc and busybox

for e500 we have should pass --without-fp to eglibc/glibc 2.19 onwards
the code is merged from eglibc into glibc upstream under nofpu/ pretext

+Create e5500 specific math_private.h and let it include when compiling for e5500/64bit core
+We prefefine __CPU_HAS_FSQRT to 0 and then in general ppc64 math_private.h we check if its
+already defined before redefining it. This way we can ensure that on e5500 builds it wont
+emit fsqrt intructions
