then all locales supported by packages are installed.

help
Whitespace seperated list of locales to allow on target.
Locales not listed here will be removed from the target.
See 'locale -a' on your host for a list of locales available
on your build host, or have a look in /usr/share/locale in
the target file system for available locales.
Notice that listing a locale here doesn't guarantee that it
will be available on the target - That purely depends on the
support for that locale in the selected packages.

Generate support for a list of locales. Locales can be
specified with or without encoding, when no encoding is
specified, UTF-8 is assumed. Examples of locales: en_US,
fr_FR.UTF-8.
# glibc and eglibc directly include gettext, so a separatly compiled
# gettext isn't needed and shouldn't be built to avoid conflicts. Some
# packages always need gettext, other packages only need gettext when
# locale support is enabled. See the documentation for how packages

If your target CPU does not have a Floating Point Unit (FPU) or a
kernel FPU emulator, but you still wish to support floating point
functions, then everything will need to be compiled with soft
floating point support (-msoft-float).

Optimizations to use when building for the target host.
NOTE: gcc optimization level is defined in build options.

Extra options to pass to the linker when building for the target.
config BR2_ECLIPSE_REGISTER
bool "Register toolchain within Eclipse Buildroot plug-in"
help
This options tells Buildroot to generate the necessary
configuration files to make your toolchain appear within
Eclipse, through the Eclipse Buildroot plugin.
