 - ncurses: various packaging fixes
 - i2c-tools: packaging changes
 - gcc: bump 4.9 series to 4.9.4
 - busybox: bump to version 1.25.0
 - elfutils: bump version to 0.166
 - glibc: bump default to version 2.23

 - kmod: bump version to 23
 - lvm2: bump version to 2.02.162
 - pciutils: bump to version 3.5.1

Configuration changes:

 - BR2_GLIBC_VERSION_2_23=y is now the default defconfigs that specified
   it do not require it set anymore.

 - The mambo and firenze defconfigs were regenerated to remove redundant
   information. The resulting .config should have no differences.
