config NATIVE_TOOLCHAIN

If enabled, OpenWrt will compile using your existing toolchain instead of compiling one

prompt "Enable an extra toolchain target architecture" if TOOLCHAINOPTS

help
Some builds may require a 'biarch' toolchain. This option
allows you to specify an additional target arch.
Most people will answer N here.
config EXTRA_TARGET_ARCH_NAME
string
default "powerpc64" if powerpc64 || TARGET_pxcab
prompt "Extra architecture name" if EXTRA_TARGET_ARCH
help
Specify the cpu name (eg powerpc64 or x86_64) of the
additional target architecture.
config EXTRA_TARGET_ARCH_OPTS
string
default "-m64" if powerpc64 || TARGET_pxcab
prompt "Extra architecture compiler options" if EXTRA_TARGET_ARCH
help
If you're specifying an addition target architecture,
you'll probably need to also provide options to make
the compiler use this alternate arch.
For example, if you're building a compiler that can build
both powerpc and powerpc64 binaries, you'll need to
specify -m64 here.

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.
