How to get a smaller toolchain from scratch?

Question

I have built a custom toolchain from scratch for a MIPS 24kc (dragino) target platform, using gcc-6.3.0, musl-1.1.16 and binutils-2.27. That toolchain is completely function

Answer 1

Fixing this issue has been simpler than expected... All toolchain binaries are installed non-stripped. So this can be fixed calling

$ make install-strip

instead of

$ make install

when you install cross-gcc (stage 2).

Size of generated toolchain is 122MB, what is nice compared with 557M of the original toolchain. So this issue is fixed! Hope this information will be useful for somebody else in the future. Thank you!
