Optimizations to use when building for the target host.
config SOFT_FLOAT
bool "Use software floating point by default" if TARGET_OPTIONS
default y if !HAS_FPU
depends on arm || armeb || powerpc || mipsel || mips || mips64el || mips64
help
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).
Most people will answer N.
config USE_MIPS16
bool "Build packages with MIPS16 instructions" if TARGET_OPTIONS
depends on HAS_MIPS16
depends on !GCC_VERSION_4_6
default y
help
If your target CPU does support the MIPS16 instruction set
and you want to use it for packages, enable this option.
MIPS16 produces smaller binaries thus reducing pressure on
caches and TLB.
Most people will answer N.

compiling one.

If enabled, OpenWrt will compile using the native toolchain for your
host instead of compiling one.

Specify the libc type used by the external toolchain. The given value
is passed as -m flag to all gcc and g++ invocations. This is mainly
intended for multilib toolchains which support glibc and uclibc at
the same time. If no value is specified, no -m flag is passed.

CPPFLAGS). Use ./DIR for directories relative to the root above.

Some builds may require a 'biarch' toolchain. This option
allows you to specify an additional target arch.
Most people will answer N here.
