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

It wont compile otherwise and fail with errors e.g.

Valgrind requires glibc version 2.2 - 2.17 ...

rootfs.py: Check for LDCONFIGDEPEND being empty string

We override LDCONFIGDEPEND to be empty string for uclibc
however the current check is for it being None as a result
the function is still executed but ldconfig-native is not
built as dependency for rootfs when building with uclibc

Fixes errors like below

File:

openssl: Fix build on uclibc

we need to map OS string correctly to include linux-uclibcspe
which is what we use with ppc+spe on uclibc, additionally move
gnuspe triplet mapping to same code as well
