When building with an external toolcahin with musl also include
./include/fortify by default. This is also done when we build with the
internal toolchain using musl libc.
Without this extra include the fortify source feature is not working
when using an external musl toolchain. All binaries were compiled
without fortify source when an external musl toolchain was used. All
binaries release done by the OpenWrt project use the internal toolcahin
where fortify source is working.

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

If your target CPU does support the MIPS16 instruction set
