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.
# 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
# should rely on the following two options.

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).

If you are building your own toolchain then select the type of
libpthreads you want to use.
Not all thread variants work with all versions of uClibc,
the "linuxthreads (stable/old)" may be a working fallback
if you need threading at all.
If you have an external binary toolchain then select the type
of libpthreads it was built with.
