Thomas Petazzoni a77e8d275f system: move locale purging options to the "System configuration" menu 
The options to purge locales and to generate locale data are currently
located in the toolchain menu. However, these options are not really
related to the toolchain per-se, they are more system-level
configuration options, much like the timezone selection option we
already have in the "System configuration" menu.

Therefore, it makes more sense to have the locale-related options in
the "System configuration" menu as well.

# The availability of __sync for 8-byte types on ARM is somewhat
# complicated:
#
# - It appeared in gcc starting with gcc 4.7.
#
# - On ARMv7, there is no problem, it can be directly implemented in
# userspace.
#
# - On < ARMv7, it requires help from the kernel. Unfortunately, the
# libgcc code implementing 8-byte __sync with the help from the
# kernel calls __write() when a failure occurs, which is a function
# internal to glibc, not available in uClibc and musl. This means
# that the 8-byte __sync operations are not available on < ARMv7
# with uClibc and musl. This problem was fixed as part of gcc
# PR68059, which was backported to the gcc 5 branch, but isn't yet
# part of any gcc 5.x release.
